Re: [zfs-discuss] 2 servers, 1 ZFS filesystem and corruptions
Hi, pool wasn't exported. server1 was rebooted (with ZFS on it). During reboot ZFS (pool) was released, and I could import it on server2 (which I have done). However, when server1 was booting up it imported pool and mounted ZFS filesystems even thou they were already imported and mounted on server2. As I said, what is interesting - if both servers are up, I cannot import pool to other server, if it is on another. However, if server is booted up it somehow avoids check if same pool is already imported on other server, which in the end leads to same pool being imported on both servers and corruption.

Hello Niksa, Friday, January 25, 2008, 9:27:17 AM, you wrote: NF Hi, NF I have this setup: NF 2xSUN V440 servers with FC adapters, installed Solaris 10u4. NF Both servers see one LUN on XP storage. NF On that LUN is created ZFS filesystem (on server1). NF If I export that ZFS filesystem on server1, I can import it on server2, and vice-versa. NF If I have imported ZFS on server1 and try to import it on NF server2, it will fail (which is correct behavior). NF However, if I export filesystem on server1, import it on server2 NF and reboot server1 - after reboot, server1 will import same ZFS NF filesystem that is at that point mounted on server2, and I get NF corruptions since both systems have same ZFS FS mounted at same time! NF Is there any way to avoid such behavior - as this issue only arrizes at server reboot? If the pool was exported it shouldn't have imported it. You sure you have actually exported it and not just unmounted? Another useful feature for you possible is 'zpool import -R ..' -- Best regards, Robert Milkowski mailto:[EMAIL PROTECTED] http://milek.blogspot.com ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

You need fix for 6282725 hostname/hostid should be stored in the label It is available in latest Nevada bits, but not yet available in Solaris 10 update.

Only difference is that server1 can be manually rebooted, and while it's still down I can mount ZFS pool on server2 even without -f option, and yet server1 when booted up still mounts at same time. Just one questiong though. Is there any ETA when this patch may be available as official Solaris 10 patch? The current ETA is an early build of s10u6. We hope to have patches available before the full update 6.
