Hello.
I have trans metadevice and its one of disk
has a failure. We have to change it.
Before we change the c2t0d0 disk, users can access the volume.
After replacement of the disk, the resync starts and 5 minutes later
the file system is unmounted...
we wait finish of the resync and run fsck to be able to remount it.
During fsck, we get a lot of errors and we answer them y...
After that, we mount it but about half size of it go to the lost+found
and we can not start the database.
All backups up to the date failure occurs has problems.
The healthy backup is before the disk failure. So, we have lost
the data for 4 days...
The problem is that the file system has a failure when the
disk goes bad..
My question is that is it possible to access the files when
the file system has problems.
