Hi, on a Solaris 10u5 box (X4500) with latest patches (Oct 8) one disk was marked as failed. We replaced it yesterday, I configured it via cfgadm and told ZFS to replace it with the replacement: cfgadm -c configure sata1/4 zpool replace atlashome c1t4d0 Initially it looked well, resilvering started, but when I looked a few hours later I found the zpool still degraded and the replacement disk was also marked as failed, but the resilvering looked complete (according to zpool status): zpool status s08:~# zpool status pool: atlashome state: DEGRADED scrub: resilver completed with 0 errors on Thu Oct 9 13:51:52 2008 config: NAME STATE READ WRITE CKSUM atlashome DEGRADED 0 0 0 raidz2 ONLINE 0 0 0 [...] raidz2 DEGRADED 0 0 0 [...] c0t4d0 ONLINE 0 0 0 replacing DEGRADED 0 3.00K 18 c1t4d0s0/o UNAVAIL 0 277 0 cannot open c1t4d0 * 0 0 0 c4t4d0 ONLINE 0 0 0 [...] * at that point this disk was OFFLINE IIRC, now it''s marked ONLINE, see below I tried to get it back online with disconnecting the SATA port and then reconnecting it. Apparently that worked (the disk is still ONLINE after more than 12 hours), but I''m still stuck in the same place. ZFS seems to think that the replacement is still going on and I don''t know how to continue. I''m currently backing up the files form that box (luckily only about 1 TB), but I would like to know how to solve this: (1) export/import the file system after the backup? (2) Destroying the pool and re-init it? (3) Anything else? Thanks a lot for a brief hint!
