Still hoping someone could point me in the right direction....right now I am doing a \
recursive find command to locate files created on July 22nd (by that user)...but \
somehow I think the files no longer exist and that is why zfs is confused.

Any ideas please????

Thanks,

Shain

Subject: Scrub error and object numbers

Hello all,
I am using Opensolaris version snv_101b and after some recent issues with a faulty \
raid card I am unable to finish an entire 'zpool scrub' to completion.

While running the scub I receive the following:

errors: Permanent errors have been detected in the following files:

        smbpool/glusterfs:<0x621b67>

I have found out that the number after the data set represents the object number of \
the file/directory in question, however I have not been able to figure out what I \
need to do next to get this cleared up.

We currently have 25TB of large files stored on this file server...so I am REALLY \
looking to avoid having to do some sort of massive backup/restore in order to clear \
this up.

Can anyone help shed some light on what I can/should do next?

Thanks in advance,

Shain
