Hi, i found some time and was able to test again.
- verify with unique uid of the device - verify with autoreplace = off Indeed autoreplace was set to yes for the pools. So I disabled the autoreplace. VOL PROPERTY VALUE SOURCE nxvol2 autoreplace off default Erased the labels on the cache disk and added it again to the pool. Now both cache disks have different guid's: # cache device in node1 r...@nex1:/volumes# zdb -l -e /dev/rdsk/c0t2d0s0 -------------------------------------------- LABEL 0 -------------------------------------------- version=14 state=4 guid=15970804704220025940 # cache device in node2 r...@nex2:/volumes# zdb -l -e /dev/rdsk/c0t2d0s0 -------------------------------------------- LABEL 0 -------------------------------------------- version=14 state=4 guid=2866316542752696853 GUID's are different. However after switching the pool nxvol2 to node1 (where nxvol1 was active), the disks picked up as cache dev's: # nxvol2 switched to this node ... volume: nxvol2 state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM nxvol2 ONLINE 0 0 0 mirror ONLINE 0 0 0 c3t10d0 ONLINE 0 0 0 c4t13d0 ONLINE 0 0 0 mirror ONLINE 0 0 0 c3t9d0 ONLINE 0 0 0 c4t12d0 ONLINE 0 0 0 mirror ONLINE 0 0 0 c3t8d0 ONLINE 0 0 0 c4t11d0 ONLINE 0 0 0 mirror ONLINE 0 0 0 c3t18d0 ONLINE 0 0 0 c4t22d0 ONLINE 0 0 0 mirror ONLINE 0 0 0 c3t17d0 ONLINE 0 0 0 c4t21d0 ONLINE 0 0 0 cache c0t2d0 FAULTED 0 0 0 corrupted data # nxvol1 was active here before ... n...@nex1:/$ show volume nxvol1 status volume: nxvol1 state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM nxvol1 ONLINE 0 0 0 mirror ONLINE 0 0 0 c3t15d0 ONLINE 0 0 0 c4t18d0 ONLINE 0 0 0 mirror ONLINE 0 0 0 c3t14d0 ONLINE 0 0 0 c4t17d0 ONLINE 0 0 0 mirror ONLINE 0 0 0 c3t13d0 ONLINE 0 0 0 c4t16d0 ONLINE 0 0 0 mirror ONLINE 0 0 0 c3t12d0 ONLINE 0 0 0 c4t15d0 ONLINE 0 0 0 mirror ONLINE 0 0 0 c3t11d0 ONLINE 0 0 0 c4t14d0 ONLINE 0 0 0 cache c0t2d0 ONLINE 0 0 0 So this is true with and without autoreplace, and with differnt guid's of the devices. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
