Re: [zfs-discuss] Checksum errors with SSD.
Dear Cindy and Edward Many thanks for your input. Indeed there is something wrong with the SSD. Smartmontools confirm me also couples of errors. So I open a case and hopefully they will replace the SSD. What I learned? - Be careful of special offers - Use also rock solid components for your homeserver - Use ZFS, Scrub regularly Best regards and many thanks for all your help and keep up the good work!

What's the confusion? Replace the drive. If you think it's a false positive (drive is not actually failing) then you would zpool clear, (or online, or whatever, until the pool looks normal again) and then scrub. If the errors come back, it definitely means the drive is failing. Or perhaps the sata cable that connects to it, or perhaps the controller. But 99% certain the drive. ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Checksum errors with SSD.
Hi Benjamin, I'm not familiar with this disk but you can see the fmstat output that disk, system event, and zfs-related diagnostics are on overtime about something and its probably this disk. You can get further details from fmdump -eV and you will probably see lots of checksum errors on this disk. You might review some of the h/w diagnostic recommendations in this wiki: http://www.solarisinternals.com/wiki/index.php/ZFS_Troubleshooting_Guide I would recommend replacing the disk, soon, or figure out what other issue might be causing problems for this disk.
