[zfs-discuss] raidz failure, trying to recover

2009-09-26 Thread Liam Slusser
Long story short, my cat jumped on my server at my house crashing two drives at the same time. It was a 7 drive raidz (next time ill do raidz2). The server crashed complaining about a drive failure, so i rebooted into single user mode not realizing that two drives failed. I put in a new 500g

Re: [zfs-discuss] Best way to convert checksums

2009-09-26 Thread Orvar Korvar
I had this same question. I was recommended to use rsync or zfs send. I used both just to be safe. With zfs send, you create a snapshot and then send the snapshot. After deleting the snapshot on the target, you have identical copies. rsync seems to be used for this task also. And also zfs send.

[zfs-discuss] Problem: ZFS Partition rewriten, how to recover data???

I had a zfs partition written using zfs113 for Mac large around 1.37 TB, then under freebsd 7.2 following a guide on wiki I had wrote 'zpool create trunk' eventually rewriting the partition. Now the question is how to recover the partition or to recover data from it? Thanks

Do you have a backup copy of your zpool.cache file? If you have that file, ZFS will happily mount a pool on boot without its slog device - it'll just flag the slog as faulted and you can do your normal replace. I used that for a long while on a test server with a ramdisk slog - and I never
