Hi, I have the following scenario: A30p <==> disk1 <==> disk2
disk1 and disk2 are identical 200GB disks in an extarnal ICE-cube case. My dmesg output is attached. After creating and mounting them as UFS2 filesystems under /mnt/a /mnt/b and starting a `iozone -s 102400m -r 1024k` in parallel under each FS I get very quickly: ... No ocb on the queue for target 0. sbp0:0:0 request timeout ... requeue sbp0:0:0 request timeout ... requeue sbp0:0:0 request timeout ... requeue sbp0:0:0 request timeout ... requeue No ocb on the queue for target 0. No ocb on the queue for target 0. No ocb on the queue for target 0. No ocb on the queue for target 0. ... The only way to get out is `fwcontrol -r`. BUT: If starting only one `iozone -s 102400m -r 1024k` in either /mnt/a or /mnt/b the command runs for several hours without problems. Do we have a problem with concurrent accesses or do I just have a HW problem. Any tips for further debugging BTW? Bye! ---- Michael Reifenberger ^.*Plaut.*$, IT, R/3 Basis, GPS
