Hi all Testing variable size 'disks' in mirror, I followed Victor Latushkin's example
bash-4.0# mkfile -n 2000000000000 d0 bash-4.0# zpool create pool $PWD/d0 bash-4.0# mkfile -n 1992869543936 d1 bash-4.0# zpool attach pool $PWD/d0 $PWD/d1 and so on - this works well. Now, to try to mess with ZFS a litt (or a lot), I tried corrupting parts of both sides of the mirror to see what ZFS would do about it r...@mime:/testpool/testdisks# dd if=/dev/urandom of=d1 bs=100k count=1 skip=30 1+0 records in 1+0 records out 102400 bytes (102 kB) copied, 0.00208301 s, 49.2 MB/s r...@mime:/testpool/testdisks# dd if=/dev/urandom of=d0 bs=100k count=1 skip=50 1+0 records in 1+0 records out 102400 bytes (102 kB) copied, 0.00205321 s, 49.9 MB/s This resulted in a panic - see below for the info from the kernel log. I'd forgotten to turn on dumps after last reinstall, but it should be easy to reproduce it. I think I read somewhere that it was normal for zfs/zpool to panic if it lost contact with a pool - is this what happened here? if so, is it possible to change this behaviour? If osol looses contact with a pool, I'd rather try to debug it and reboot myself if I want to, rather than having the system automatically panic.
