Lost Mirror, have backup

I need some help. I can not seem to recover my server.

I have a mirrored array of my root disk, c0d0. I was playing with ZFS and I lost the array some how.

I have a backup of the full disk taken with TAR.

Whenever I try and restore to disk from single user booting with CD I get write errors. I can not find a resoure on google.

Any ideas will help. I would like to restore the system as it was if possible.

Thanks

Use tar command as follows to retrieve tape drive backup to current directory:
(a) Change directory where you would like to restore files:

# cd /path/to/restore
# pwd
(b) Now, do a restore from tape:

# tar xvf /dev/rmt/0

if you are playing with zfs, maybe your disk is reformatted with an EFI label.

check the label using the format command / select the disk / then fdisk.

Not sure, but isn't in single user mode file system mounted as a read only under /a/file_system?

after booting to single user mode, the OS will try to mount the root volume it found on /a.

kindly post the error message that you got when restoring so we will have clear idea on whats the problem. Smilie
