https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D219760 --- Comment #5 from Henric Jungheim <henric_jungheim@yahoo.com> --- (In reply to Edward Tomasz Napierala from comment #4) The ada4 and ada3 disks were added because the existing mirror set in the p= ool was full (as in "getting out of disk space errors", not "uncomfortably high= "), so they are not likely to see any significant writes. This is a home NAS s= etup and while I have backups in the cloud and some on LTO3 tapes, I don't have anywhere local I can store what is on those drives so I'm really reluctant = to pull those drives. I was not able to find any firmware updates for those drives. Both long and short SMART tests have been run w/o finding anything. Writing multiple 1TB files to files with "dd if=3D/dev/random" hasn't caused any problems. I'll= try doing those "dd"s to zdevs next. The "write a couple TB, then scrub," test= ing takes a while; any thoughts on other non-destructive testing I could do? Is there some sane way to get a list of what the actual errors are in the p= ool (offset on the raw disk or such)? When I've done the backup, both drives h= ave always reported the same number of errors. If both drives report exactly t= he same (bad) data at the same locations, then that could perhaps suggest something useful? I have both the chipset SATA ports and SAS/SATA ports from the motherboards= LSI SAS controller. I might be able to move the drives from one controller to = the other. Another device--a Server 2008 R2 box--has been doing similar iSCSI backups = to another pool in the system for years. It, however, has much less to write = and does so from spinning rust instead of SSD (although, I would assume the GigE link is still the bottleneck). The drives for this other pool are on the s= ame controller as ada3 and ada4. I'll see about having it do an extra backup or two to the "tank" pool to see if it causes any grief there.
