Any idea ? I'm trying to fix it, but I don't see any specific interaction between raid5 and istd. Does anyone try to reproduce this bug on another arch than sparc64 ? I only use sparc32 and 64 servers and I cannot test on other archs. Of course, I have a laptop, but I cannot create a raid5 array on its internal HD to test this configuration ;-) Please note that I won't read my mails until next saturday morning (CEST). > After disconnection of iSCSI target : > > Tasks: 232 total, 7 running, 224 sleeping, 0 stopped, 1 zombie > Cpu(s): 0.0%us, 15.2%sy, 0.0%ni, 84.3%id, 0.0%wa, 0.1%hi, 0.3%si, > 0.0%st > Mem: 4139032k total, 4127584k used, 11448k free, 95752k buffers > Swap: 7815536k total, 0k used, 7815536k free, 3758792k cached > > PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND > 9738 root 15 -5 0 0 0 R 100 0.0 4:56.82 md_d0_raid5 > 9774 root 15 -5 0 0 0 R 100 0.0 5:52.41 istd1 > 9739 root 15 -5 0 0 0 R 14 0.0 0:28.90 md_d0_resync > 9916 root 20 0 3248 1544 1120 R 2 0.0 0:00.56 top > 4129 root 20 0 41648 5024 2432 S 0 0.1 2:56.17 > fail2ban-server > 1 root 20 0 2576 960 816 S 0 0.0 0:01.58 init > 2 root 15 -5 0 0 0 S 0 0.0 0:00.00 kthreadd > 3 root RT -5 0 0 0 S 0 0.0 0:00.00 migration/0 > 4 root 15 -5 0 0 0 S 0 0.0 0:00.02 ksoftirqd/0 > 5 root RT -5 0 0 0 S 0 0.0 0:00.00 migration/1 > 6 root 15 -5 0 0 0 S 0 0.0 0:00.00 ksoftirqd/1 Regards, JKB
