Maybe there are too many I/Os for this controller. You may try this settings B130 echo zfs_txg_synctime_ms/W0t2000 | mdb -kw echo zfs_vdev_max_pending/W0t5 | mdb -kw older versions echo zfs_txg_synctime/W0t2 | mdb -kw echo zfs_vdev_max_pending/W0t5 | mdb -kw Andreas -- This message posted f

I was frustrated with this problem for months. I've tried different disks, cables, even disk cabinets. The driver hasn't been updated in a long time. When the timeouts occurred, they would freeze for about a minute or two (showing the 100% busy). I even had the problem with less than 8 L

Any news regarding this issue? I'm having the same problems. I'm using an external Axus SCSI enclosure (Yotta with 16 drives) and it timed out on scanning LUNs (16 of them b/c Yotta is configured as JBOD). I've performed firmware upgrade to the Yotta system and now the scanning works, the pool

Hi, I'm having trouble with scsi timeouts, but it appears to only happen when I use ZFS. I've tried to replicate with SVM, but I can't get the timeouts to happen when that is the underlying volume manager, however the performance with ZFS is much better when it does work. The symptom is tha
