I am wondering if this is really a hardware issue somewhere. In the mean time, I had deleted a number of old files and snapshots that reclaimed space and the errors have greatly diminished. Is it possible these errors are made worse when one drive in a PMP slows things down with a bunch of write errors. On another note, the other issue I have noticed is at boot up time, the last set of disks on pmp2 does not scan until late in the boot process. What is the best way to work around this, so all is scanned before zfs tries to mount things. In dmesg, I see a (noperiph:siisch1:0:-1:ffffffff): rescan already queued (noperiph:siisch3:0:-1:ffffffff): rescan already queued so later on I see .... Trying to mount root from ufs:/dev/da2s1a [rw]... ZFS filesystem version: 5 ZFS storage pool version: features support (5000) pmp2 at siisch0 bus 0 scbus0 target 15 lun 0 pmp2: <Port Multiplier 47261095 1f06> ATA-0 device pmp2: 300.000MB/s transfers (SATA 2.x, NONE, PIO 8192bytes) pmp2: 5 fan-out ports ada12 at siisch0 bus 0 scbus0 target 1 lun 0 I had to do a /etc/rc.d/zfs restart once the box was up. -- ------------------- Mike Tancsa, tel +1 519 651 3400 Sentex Communications, mike@sentex.net Providing Internet services since 1994 www.sentex.net Cambridge, Ontario Canada http://www.tancsa.com/
