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.

Dear Forum
I use a KINGSTON SNV125-S2/30GB SSD on a ASUS M3A78-CM Motherboard (AMD SB700
Chipset).
SATA Type (in BIOS) is SATA
Os : SunOS homesvr 5.11 snv_134 i86pc i386 i86pc
When I scrub my pool I got a lot of checksum errors :
NAME STATE READ WRITE CKSUM
rpool DEGRADED 0 0 5
c8d0s0 DEGRADED 0 0 71 too many errors
zpool clear rpool works after a scrub I have again the same situation.
fmstat looks like this :

Problem in : zfs://pool=rpool/vdev=f7dad7554a72b3bc

In /var/adm/messages I don''t have any abnormal issues.
I can put the SSD also on a other SATA-Port but without success.
My other HDD runs smoothly :
NAME STATE READ WRITE CKSUM

mirror-0 ONLINE 0 0 0
c4d1 ONLINE 0 0 0
c5d0 ONLINE 0 0 0
iostat gives me following :

Any hints?
Best regards and many thanks for your help!

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.
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!

Dear Forum Just technical infos for all who have the same problem with AMD Chipset and Kingston SSDs. Official statement from Kingston : We have 2 major problem sources: - chipset comes from AMD (there is no better chipset for SSDs than Intel) - your OS is not Windows (in which case all drivers for storage, chipset and BIOS have to be installed manually) Also there are other issues in Linux forums : The SSD worked for a little while, and then failed completely. It appeared to work on an Intel based machine, but my AMD 780G machine was not happy at all. I even went through the hassle of installing Windows XP to see if it worked there, but XP didn''t even see the drive. Note that my other machine appeared to work fine with the SSD, so I think it''s sort of SB700/SSD interaction. Others have reported issues on the forum as well. Hope that helps.
