filesystems

according to Percona:

Unmount the filesystem or make it read-only if...
You have filesystem corruption OR
You have dropped tables in innodb_file_per_table format

If I have innodb_file_per_table enabled, and accidently dropped a table, while the datadir is mounted as within the / partition , can data still be recovered? Obviously you can't work with an unmounted root filesystem.

Our VPS host has a defaulted filesystem table which we cannot customize. I was wondering in case of any future scenario.

edit: would mounting the / filesystem through NFS onto another system as read-only be a workaround?

TIA.
