  • Disk / system configuration for log collection / syslog server

    - by Konrads
    I am looking into building a syslog / logging infrastructure and am pondering about some architecture best practices. Essentially, I see that a syslog system needs to support two conflicting workloads: log collection. Potentially massive streams of data need to be written quickly to disks and indexed. log querying. logs will be queried by both fixed fields such as date and source as well as text search. What is the best disk/system setup assuming I'd like to keep it to a single server for now? Should I use SSDs or ramdisk to off-load some processing? some disks in stripe and some in raid5? I am particularly eyeing Graylog2 with ElasticSearch/MongoDB

  • Need to Extend Volume

    - by Roger Galindo
    Ok Here is where I am... I have an HP Proliant with 8 Drives configured as RAID5, and C:\Drive Disk 0 and D:\ drive Disk 1. I need to add more space to Disk 0 (C:) and have 150GB available on Disk 1 (D:). I tested the Disk Mgmt on D:\ and freed up 4GB which now shows to be Unallocated. How do I add the 4GB of Unallocated to the c:\? When I click on C:\ the Menu shows "Extend Volume" as Grayed Out not Black but the D:\ Drive shows Extend Volume as selectable/black.

  • Changed array composition, mdadm --detail still shows the old array size

    - by Prody
    I have a machine with 8 disks. I installed it with my hoster's install automation (it's OVH, I don't have physical access to it). The machine installed correctly, but it made an array that I wanted to change. It created a raid5 array across 5/8 disks and I've changed it to raid10 across 8 disks. I've done this by first --stopping the old array and then --creating the new array. It warned me that a previous array was there, but I chose to continue. So it created the array, spent 10ish hours syncing it and now that it's ready I get this strange behavior: When I fdisk p on it, I see the correct size. But when I mdadm --detail it I see the old array's size even tho I get the new composition and level. When I try to pvcreate on it, i get the old size again for some reason. Did I have to do something else? Did I miss something?

  • Can I get redundancy with a JBOD storage subsystem

    - by Dat Chu
    I have a Promise Technology J610S. This is a JBOD subsystem. Is it possible for me to buy a SAS hardware RAID controller and provide some type of redundancy for these drives? I am unsure whether I will use Linux or Windows yet so an answer with enumeration for both would be highly appreciated. One solution that I thought of was: if my J610s can export each drive as a target, my server will simply see 16 drives. The RAID controller can then perform the RAID5/RAID6 if I want.

  • What does the the reconstruction process of mdadm do exactly on raid10

    - by Azrael
    I've got a system with 4 disks set up as raid10. All disks are usable, and mdadm all states them with UUUU. Due to a recent system crash, the raid is currently reconstruction the raid as it was marked as "not clean," and a reconstruction process was started. On a closer look smartctl shows problems on one disk: sd 0:0:0:0: [sda] Unhandled sense code sd 0:0:0:0: [sda] Result: hostbyte=DID_OK driverbyte=DRIVER_SENSE sd 0:0:0:0: [sda] Sense Key : Medium Error [current] [descriptor] Descriptor sense data with sense descriptors (in hex): 72 03 11 04 00 00 00 0c 00 0a 80 00 00 00 00 00 24 cd 78 d4 sd 0:0:0:0: [sda] Add. Sense: Unrecovered read error - auto reallocate failed sd 0:0:0:0: [sda] CDB: Read(10): 28 00 24 cd 75 1e 00 04 00 00 With a research about the reconstruction process, I only found information concerning raid5 but nothing for raid10. Can I replace this problematic disk during the reconstruction process, or will I kill the raid with this?

  • mdadm - Recovering a 'split' RAID1 array

    - by Hamza
    I have two drives that used to be part of a single RAID1 volume but it appears that one of them went offline for some time, something I've noticed just now when I rebooted my system. I now seem to have two RAID volumes, as reported by: # cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md126 : active raid1 sdc[1] 2096116 blocks super 1.2 [2/1] [_U] md127 : active (auto-read-only) raid1 sdb[0] 2096116 blocks super 1.2 [2/1] [U_] unused devices: <none> Not exactly sure where to go from here. How can I merge and re-sync these volumes without data loss? Thanks.

  • Terminal Server 2003 Performance Troubleshooting

    - by MikeM
    Let me get your thoughts on terminal server performance problems. The server hosts average 25 users which, after running some numbers, on average use 600MB memory with their main applications running (web browser, adobe reader, IP phone client). All users are on the same LAN as server. We constantly experience slow response and short session lockups. Combined CPU usage is on average 10%. What appears strange to me is that the system shows 29GB physical memory with 25GB of it free. The page file usage is about 50% averaging 9GB used. Some server specs OS: Server 2003 32bit Enterprise with /PAE flag RAM: 32GB CPU: 2xQuad Core @ 2.27Ghz HD: RAID5 1.2GB After doing basic troubleshooting using performance monitor it leads me to believe that the performance problems are caused by the 32bit OS limitation in addressing full 32GB of physical memory even though the /PAE flag is used. Can anyone suggest something, troubleshooting steps that can lead to a more conclusive answer? Thanks

  • Server drives: 2.5" SCSI less reliable than 3.5" ?

    - by Bill
    Just had an HP 2.5" SAS 10k drive fail on a RAID5 array after about 2.5 years. It made me wonder if this was a fluke or an indication that 2.5" drives are less reliable than 3.5" SAS drives. I've had many 3.5" SAS drives running for many years without any issues (knock on wood). I would think that smaller drives would generate less heat and therefore be more reliable, but couldn't find any evidence of this. I realize all drives will eventually fail and that it's a crap shoot with any particular model, but was hoping someone could point out some related studies or comment on the SCSI drive sizes they've found to be most reliable in servers. Thanks.

  • Windows Server 2008 R2 and OSX 10.5/.6/.7

    - by Keith Loughnane
    I'm handling a migration from a on old mac server to a Windows Server 2008 R2 machine running a 12TB(10 usable) RAID5 server. It's using an SMB share and now the OSX 10.5/.6 users can search sometimes it works but takes up to 10 minutes. The OSX 10.7 machine seems to be fine. I've looked in the root of the shared drive for a .Spotlight-V100 file (ls -a) but it doesn't seem to be there. mdutil says indexing is on for that volume and I have cleared the index using mdutil -E /Volumes/MeSharedVolume numerous times. Any ideas?

  • raid 5 creation (using mdadm) lots of read/writes on creation: is this normal?

    - by Gbrits
    I created a software raid 5 disk using: mdadm -C /dev/md2 -l5 -n4 /dev/sd[i-l] at the same time I'm using dstat to see io-activity: dstat -c -d -D total,sda1,md2,sdi,sdj,sdk,sdl -l -m -n and notice that disks sd[i-k] are all read from and sdl is written to. Now, I do understand that raid5 has to be configured, but it takes a really long time and all disks are clean & formatted (using xfs) so I figure there might be some kind of shortcut to skip (unnecessary? ) checking.. Is it? The creation is part of a time-critical nightly batch-process (run on amazon ec2) so it's not a one-time thing. Thanks, Geert-Jan

  • I have a 21TB array but only 16TB is visible from Windows

    - by Relentim
    CONTROLLER Raid Controller: 3Ware 9650SE-24M8 Disks: 21 x 1TB RAID5 Stripe 64KB WINDOWS OS: Windows Server 2003 SP2 32x Disk: Dynamic 19557.44GB Volume: Capacity 15832.19GB I guess my array must have a 4KB block size which is limiting it to 16TB. I think I would have to switch to a 64KB block size to be able to see a maximum of 256TB. Or create another unit on my controller to go above 16TB of storage. Unfortunately I have already added over 16TB, ideally I would like to shrink the array and reclaim the 5 disks that aren't doing anything. I don't think this is possible. More likely, can I change the block size so 20TB becomes visible in windows?

  • When using RAID10 + BBWC why is it better to separate PostgreSQL data files from OS and transaction logs than to keep them all on the same array?

    - by Vlad
    I've seen the advice everywhere (including here and here): keep your OS partition, DB data files and DB transaction logs on separate discs/arrays. The general recommendation is to use RAID1 for OS, RAID10 for data (or RAID5 if load is very read-biased) and RAID1 for transaction logs. However, considering that you will need at least 6 or 8 drives to build this setup, wouldn't a RAID10 over 6-8 drives with BBWC perform better? What if the drives are SSDs? I'm talking here about internal server drives, not SAN.

  • Disable writing RAID degraded mode

    - by jolivier
    I have a RAID5 with 5 disks on my machine and suspect the motherboard chipset to fail at some points and make my raid going in degraded mode. Last time it happened I noticed it on the failure of the 2nd drive connected to the same chipset and lost a lot of data. So I would like to prevent this, and especially I would like to have mdadm disable writes on the raid if one of the disk fails. So that in between I get notified, I recover and can use my system again. Sadly I could not find it in man mdadm so I was wondering if this is possible via a tool or hidden option since for me it looks like a standard feature of a RAID system. If this is not possible I would also be happy with a solution to stop the raid if degraded.

  • format/build raid 5 with one 4k drive, three 512b

    - by skidawgz
    I have 4 WD 1TB drives which I want to 4x1TB Raid5. I am not sure what course of action to take next. How do I configure my 4th drive (sde) to align with the rest? Will this affect performance? I rcv this msg (which brings me here to ask these question): The device presents a logical sector size that is smaller than the physical sector size. Aligning to a physical sector (or optimal I/O) size boundary is recommended, or performance may be impacted. fdisk -l shows: Disk /dev/sdb: 1000.2 GB, 1000204886016 bytes 81 heads, 63 sectors/track, 382818 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xf324ba09 Device Boot Start End Blocks Id System /dev/sdb1 2048 1953525167 976761560 fd Linux raid autodetect Disk /dev/sdc: 1000.2 GB, 1000204886016 bytes 81 heads, 63 sectors/track, 382818 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x38bcc1f0 Device Boot Start End Blocks Id System /dev/sdc1 2048 1953525167 976761560 fd Linux raid autodetect Disk /dev/sdd: 1000.2 GB, 1000204886016 bytes 81 heads, 63 sectors/track, 382818 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x570f77e7 Device Boot Start End Blocks Id System /dev/sdd1 2048 1953525167 976761560 fd Linux raid autodetect Disk /dev/sde: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0xeb665e7b Device Boot Start End Blocks Id System

  • mdadm starts resync on every boot

    - by Anteru
    Since a few days (and I'm positive it started shortly before I updated my server from 13.04-13.10) my mdadm is resyncing on every boot. In the syslog, I get the following output [ 0.809256] md: linear personality registered for level -1 [ 0.811412] md: multipath personality registered for level -4 [ 0.813153] md: raid0 personality registered for level 0 [ 0.815201] md: raid1 personality registered for level 1 [ 1.101517] md: raid6 personality registered for level 6 [ 1.101520] md: raid5 personality registered for level 5 [ 1.101522] md: raid4 personality registered for level 4 [ 1.106825] md: raid10 personality registered for level 10 [ 1.935882] md: bind<sdc1> [ 1.943367] md: bind<sdb1> [ 1.945199] md/raid1:md0: not clean -- starting background reconstruction [ 1.945204] md/raid1:md0: active with 2 out of 2 mirrors [ 1.945225] md0: detected capacity change from 0 to 2000396680192 [ 1.945351] md: resync of RAID array md0 [ 1.945357] md: minimum _guaranteed_ speed: 1000 KB/sec/disk. [ 1.945359] md: using maximum available idle IO bandwidth (but not more than 200000 KB/sec) for resync. [ 1.945362] md: using 128k window, over a total of 1953512383k. [ 2.220468] md0: unknown partition table I'm not sure what's up with that detected capacity change, looking at some old logs, this does have appeared earlier as well without a resync right afterwards. In fact, I let it run yesterday until completion and rebooted, and then it wouldn't resync, but today it does resync again. For instance, yesterday I got: [ 1.872123] md: bind<sdc1> [ 1.950946] md: bind<sdb1> [ 1.952782] md/raid1:md0: active with 2 out of 2 mirrors [ 1.952807] md0: detected capacity change from 0 to 2000396680192 [ 1.954598] md0: unknown partition table So it seems to be a problem that the RAID array does not get marked as clean after every shutdown? How can I troubleshoot this? The disks themselves are both fine, SMART tells me no errors, everything ok.

  • LUKS no longer accepts my my passphrase

    - by Two Spirit
    I created a 4 drive RAID5 setup using mdadm and upgrading from 2TB drives to the new Hitachi 7200RPM 4TB drives. I can initially open my luks partition, but later can no longer access it. I can no longer access my LUKS partition even tho I have the right passphrases. It was working and then at an unknown point in time loose access to LUKS. I've used the same procedures for upgrading from 500G to 1TB to 1.5TB to 2TB. After the first time this happened a week ago, I thought maybe there was some corruption so I added a 2nd Key as a backup. After the second time the LUKS became unaccessible, none of the keys worked. I put LUKS on it using cryptsetup -c aes -s 256 -y luksFormat /dev/md0 # cryptsetup luksOpen /dev/md0 md0_crypt Enter LUKS passphrase: Enter LUKS passphrase: Enter LUKS passphrase: Command failed: No key available with this passphrase. The first time this happened while I was upgrading to 4TB drives, I thought it was a fluke, and ultimately had to recover from backups. I went an used luksAddKey to add a 2nd key as a backup. It happened again and I tried both passphrases, and neither worked. The only thing I'm doing differently this time around is that I've upgraded to 4TB drives which use GPT instead of fdisk. The last time I had to even reboot the box was over 2 years ago. I'm using ubuntu-8.04-server with kernel 2.6.24-29 and upgraded to -2.6.24-31, but that didn't fix the problem.

  • How to re-add RAID-10 dropped drive?

  • Switching mdadm to an external bitmap

    - by Oli
    I've just read this in another post about improving RAID5/6 write speeds: After increasing stripe cache & switching to external bitmap, my speeds are 160 Mb/s writes, 260 Mb/s reads. :-D I've already found out how to increase the stripe cache and this worked pretty well but I'd like to know more about an external bitmap. I have an incredibly fast (540MB/s) RAID0 SSD that would do well if a bitmap does what I think it does but I'm still very unsure. I've only known about them as long as I've known this post. A few questions: What is a bitmap (in terms of mdadm)? What are the advantages of an internal bitmap (over external)? What are the advantages of an external bitmap (over internal)? How do I switch between the two? I should add that while this is a I'm-bored-let's-break-something thread, I do value the data stored on the RAID array. If doing this is going to put data at significant risk, please let me know.

  • Can't start system due to mdadm failing

    - by user101212
    I used to have a 5-disk RAID5 partition, all working very well. I have then decided to add 3 more disks on it, totaling 8 equal disks. I've opened Webmin and just asked to add the disks. Then I've realized the three disks had NTFS partitions, wich mdadm didn't complain, so I tried to stop the growing to remove the Windows partitions. I've tried to remove a disk using the same Webmin, but (as you might guess and call me fool...), the system became unstable. By restarting the system, I've started receiving these messages: "udev[126]: timeout: killing '/sbin/mdadm --incremental /dev/sdh1' [311]" "udev[124]: timeout: killing '/sbin/mdadm --detail --export /dev/md0' [316]" I've formated the system disk, hoping to get a system up and running. I did that with all RAID disks disconected, so everything was fine. I then reconnected the disks, wich was also ok. And finally installed mdadm using apt-get. By reboot, the system has found the mdadm intention of growing the system, so the same messages appear again. I other words: I can't even reach a command prompt to do something. Any ideas of what to do? I believe I could turn off the system, disconnect the disks and look for the mdadm.conf file. Would that be a good idead? I'm no Linux expert, so I'm really lost here.

  • sql perfomance on new server

    - by Rapunzo
    My database is running on a pc (AMD Phenom x6, intel ssd disk, 8GB DDR3 RAM and windows 7 OS + sql server 2008 R2 sp3 ) and it started working hard, timeout problems and up to 30 seconds long queries after 200 mb of database And I also have an old server pc (IBM x-series 266: 72*3 15k rpm scsi discs with raid5, 4 gb ram and windows server 2003 + sql server 2008 R2 sp3 ) and same query start to give results in 100 seconds.. I tried query analyser tool for tuning my indexed. but not so much improvements. its a big dissapointment for me. because I thought even its an old server pc it should be more powerfull with 15k rpm discs with raid5. what should I do. do I need $10.000 new server to get a good performance for my sql server? cant I use that IBM server? Extra information: there is 50 sql users and its an ERP program. There is my query ALTER FUNCTION [dbo].[fnDispoTerbiye] ( ) RETURNS TABLE AS RETURN ( SELECT MD.dispoNo, SV.sevkNo, M1.musteriAdi AS musteri, SD.tipTurId, TT.tipTur, SD.tipNo, SD.desenNo, SD.varyantNo, SUM(T.topMetre) AS toplamSevkMetre, MD.dispoMetresi, DT.gelisMetresi, ISNULL(DT.fire, 0) AS fire, SV.sevkTarihi, DT.gelisTarihi, SP.mamulTermin, SD.miktar AS siparisMiktari, M.musteriAdi AS boyahane, MD.akisNotu AS islemler, --dbo.fnAkisIslemleri(MD.dispoNo) DT.partiNo, DT.iplikBoyaId, B.tanimAd AS BoyaTuru, MAX(HD.hamEn) AS hamEn, MAX(HD.hamGramaj) AS hamGramaj, TS.mamulEn, TS.mamulGramaj, DT.atkiCekmesi, DT.cozguCekmesi, DT.fiyat, DV.dovizCins, DT.dovizId, (SELECT CASE WHEN DT.dovizId = 2 THEN CAST(round(SUM(T .topMetre) * DT.fiyat * (SELECT TOP 1 satis FROM tblKur WHERE dovizId = 2 ORDER BY tarih DESC), 2) AS numeric(18, 2)) WHEN DT.dovizId = 3 THEN CAST(round(SUM(T .topMetre) * DT.fiyat * (SELECT TOP 1 satis FROM tblKur WHERE dovizId = 3 ORDER BY tarih DESC), 2) AS numeric(18, 2)) WHEN DT.dovizId = 1 THEN CAST(round(SUM(T .topMetre) * DT.fiyat * (SELECT TOP 1 satis FROM tblKur WHERE dovizId = 1 ORDER BY tarih DESC), 2) AS numeric(18, 2)) END AS Expr1) AS ToplamTLfiyat, DT.aciklama, MD.dispoNotu, SD.siparisId, SD.siparisDetayId, DT.sqlUserName, DT.kayitTarihi, O.orguAd, 'Çözgü=(' + (SELECT dbo.fnTipIplikler(SD.tipTurId, SD.tipNo, SD.desenNo, SD.varyantNo, 1) AS Expr1) + ')' + ' Atki=(' + (SELECT dbo.fnTipIplikler(SD.tipTurId, SD.tipNo, SD.desenNo, SD.varyantNo, 2) AS Expr1) + ')' AS iplikAciklama, DT.prosesOk, dbo.[fnYikamaTalimat](SP.siparisId) yikamaTalimati FROM tblDoviz AS DV WITH(NOLOCK) INNER JOIN tblDispoTerbiye AS DT WITH(NOLOCK) INNER JOIN tblTanimlar AS B WITH(NOLOCK) ON DT.iplikBoyaId = B.tanimId AND B.tanimTurId = 2 ON DV.id = DT.dovizId RIGHT OUTER JOIN tblMusteri AS M1 WITH(NOLOCK) INNER JOIN tblSiparisDetay AS SD WITH(NOLOCK) INNER JOIN tblDispo AS MD WITH(NOLOCK) ON SD.siparisDetayId = MD.siparisDetayId INNER JOIN tblTipTur AS TT WITH(NOLOCK) ON SD.tipTurId = TT.tipTurId INNER JOIN tblSiparis AS SP WITH(NOLOCK) ON SD.siparisId = SP.siparisId ON M1.musteriNo = SP.musteriNo INNER JOIN tblTip AS TP WITH(NOLOCK) ON SD.tipTurId = TP.tipTurId AND SD.tipNo = TP.tipNo AND SD.desenNo = TP.desen AND SD.varyantNo = TP.varyant INNER JOIN tblOrgu AS O WITH(NOLOCK) ON TP.orguId = O.orguId INNER JOIN tblMusteri AS M WITH(NOLOCK) INNER JOIN tblSevkiyat AS SV WITH(NOLOCK) ON M.musteriNo = SV.musteriNo INNER JOIN tblSevkDetay AS SVD WITH(NOLOCK) ON SV.sevkNo = SVD.sevkNo ON MD.mamulDispoHamSevkno = SV.sevkNo LEFT OUTER JOIN tblTop AS T WITH(NOLOCK) INNER JOIN tblDispo AS HD WITH(NOLOCK) ON T.dispoNo = HD.dispoNo AND T.dispoTuruId = HD.dispoTuruId ON SVD.dispoTuruId = T.dispoTuruId AND SVD.dispoNo = T.dispoNo AND SVD.topNo = T.topNo AND MD.siparisDetayId = HD.siparisDetayId ON DT.dispoTuruId = MD.dispoTuruId AND DT.dispoNo = MD.dispoNo LEFT OUTER JOIN tblDispoTerbiyeTest AS TS WITH(NOLOCK) ON DT.dispoTuruId = TS.dispoTuruId AND DT.dispoNo = TS.dispoNo --WHERE DT.gelisTarihi IS NULL -- OR DT.gelisTarihi > GETDATE()-30 GROUP BY MD.dispoNo, DT.partiNo, DT.iplikBoyaId, TS.mamulEn, TS.mamulGramaj, DT.gelisMetresi, DT.gelisTarihi, DT.atkiCekmesi, DT.cozguCekmesi, DT.fire, DT.fiyat, DT.aciklama, DT.sqlUserName, DT.kayitTarihi, SD.tipTurId, TT.tipTur, SD.tipNo, SD.desenNo, SD.varyantNo, SD.siparisId, SD.siparisDetayId, B.tanimAd, M.musteriAdi, M.musteriAdi, M1.musteriAdi, O.orguAd, TP.iplikAciklama, SD.miktar, MD.dispoNotu, SP.mamulTermin, DT.dovizId, DV.dovizCins, MD.dispoMetresi, MD.akisNotu, SV.sevkNo, SV.sevkTarihi, DT.prosesOk,SP.siparisId )

  • Did I lost my RAID again?

    - by BarsMonster
    Hi! A little history: 2 years ago I was really excited to find out that mdadm is so powerful so it even can reshape arrays so you can start with a smaller array and the grow it as you need. I've bought 3x1Tb drives and made RAID-5. It was fine for a year. Then I bought 2x more, and tried to reshape to RAID-6 out of 5 drives, and due to some mess with superblock versions, lost all content. Had to rebuild it from scratch, but 2Tb of data were gone. Yesterday I bought 2 more drives, and this time I had everything: properly built array, UPS. I've disabled write intent map, added 2 new drives as a spare and run a command to grow array to 7-disk. It started working, but speed was ridiculously slow, ~100kb/sec. AFter processing first 37Mb at such an amasing speed, one of old HDDs fails. I properly shutdown PC and disconnected failed drive. After bootup it appeared it recreated intent map as it was still in mdadm config, so I removed it from config and rebooted again. Now all I see is that all mdadm processes deadlocks, and don't do anything. PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1937 root 20 0 12992 608 444 D 0 0.1 0:00.00 mdadm 2283 root 20 0 12992 852 704 D 0 0.1 0:00.01 mdadm 2287 root 20 0 0 0 0 D 0 0.0 0:00.01 md0_reshape 2288 root 18 -2 12992 820 676 D 0 0.1 0:00.01 mdadm And all I see in mdstat is: $ cat /proc/mdstat Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10] md0 : active raid6 sdb1[1] sdg1[4] sdf1[7] sde1[6] sdd1[0] sdc1[5] 2929683456 blocks super 1.2 level 6, 1024k chunk, algorithm 2 [7/6] [UU_UUUU] [>....................] reshape = 0.0% (37888/976561152) finish=567604147.2min speed=0K/sec I've already tried mdadm 2.6.7, 3.1.4 and 3.2 - nothing helps. Did I lost my data again? Any suggestions how can I make it work? OS is Ubuntu Server 10.04.2... PS. Needless to say that data is unaccessible - I cannot mount /dev/md0 as save the most valuable data. You can see my disappointment - the very specific thing I was excited about failed twice taking 5Tb of my data with it.

  • 13.10 upgrade dropping wifi [on hold]

    Almost a complete newb here. After my last upgrade from 12.04 to 13.10 my wifi now randomly drops. The only way I can get a signal back is a shutdown and restart otherwise it shows no network is even available to connect to. Had no problems until the upgrade. Any help would be appreciated.

  • RAID 5 - DELL 2850 and others

    - by Kiara
    I have installed Ubuntu on a DELL 2850 and I have configured an array of 5 disks (SCSI 73GB 10K) in RAID5. I wanted to simulate a drive error so in the middle of something I just took one of the drives out and put it back again after a bit. Then the drive shows an orange light and seems to be rebuilding but actually is taking hours and hours with no results. So I went to the PERC utility (Ctrl+M) and the disk shows "REBLD". But it never gets to an online state. So I went to Objects - Physical drives - Rebuilding - View rebuild process. And in here I can see a bar moving from 0%... but if I reboot before finishing and get into the PERC Utility again, it seems to start again rebuilding from 0% - so it is not rebuilding automatically. My concern is: what would happen in a real situation? Do I have to just switch the server off and go to the Perc utility to start the rebuilding manually? I thought the whole point was to have this done automatically and without the need of stopping the server. Or does it perhaps rebuild automatically indeed but needs to have enough time without rebooting because otherwise the rebuilding process will start from scratch? It seems to take more than 3h for a 73gb disk! My second question is: can I mix then hard drives? So if I have a RAID of 5x73GB 10K can I use different size (146GB) or speeds (15K)? Apparently someone said it is OK in here Poweredge 2850: replace disk with larger in RAID?

  • How can I fix my corrupted RAID1 ext4 partition on a Synology DS212 NAS?

    - by Neil
    I have two identical 3 TB disks that were in a RAID1 array, where one disk crashed. I replaced the failed disk, but not after the RAID partitions got messed up. I need to figure out how to restore the RAID array and get at my ext4 partition. Here are the properties of the surviving disk: # fdisk -l /dev/sda fdisk: device has more than 2^32 sectors, can't use all of them Disk /dev/sda: 2199.0 GB, 2199023255040 bytes 255 heads, 63 sectors/track, 267349 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 1 267350 2147483647+ ee EFI GPT # parted /dev/sda print Model: ATA ST3000DM001-9YN1 (scsi) Disk /dev/sda: 3001GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 131kB 2550MB 2550MB ext4 raid 2 2550MB 4698MB 2147MB linux-swap(v1) raid 5 4840MB 3001GB 2996GB raid I replaced the failed drive, and cloned the surviving drive to it so I have something to work with. I cloned the drives with dd if=/dev/sdb of=/dev/sda conv=noerror bs=64M, and now /dev/sda and /dev/sdb are identical. Here is the RAID information: # cat /proc/mdstat Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] md1 : active raid1 sdb2[1] 2097088 blocks [2/1] [_U] md0 : active raid1 sdb1[1] 2490176 blocks [2/1] [_U] unused devices: <none> It seems that md2 is missing. Here is what testdisk 6.14-WIP finds: Disk /dev/sda - 3000 GB / 2794 GiB - CHS 364801 255 63 Current partition structure: Partition Start End Size in sectors 1 P Linux Raid 256 4980735 4980480 [md0] 2 P Linux Raid 4980736 9175039 4194304 [md1] Invalid RAID superblock 5 P Linux Raid 9453280 5860519007 5851065728 5 P Linux Raid 9453280 5860519007 5851065728 # After a quick search Disk /dev/sda - 3000 GB / 2794 GiB - CHS 364801 255 63 Partition Start End Size in sectors D MS Data 256 4980607 4980352 [1.41.12-2197] D Linux Raid 256 4980735 4980480 [md0] D Linux Swap 4980736 9174895 4194160 D Linux Raid 4980736 9175039 4194304 [md1] >P MS Data 9481056 5858437983 5848956928 [1.41.12-2228] And listing the files on the last partition in the list shows all of my files intact. What should I do?
