Hi, my backup system (running backuppc) has developed a weird problem: calls from command line "mdadm --detail /dev/mdX" block, for every existing raid on the system, and can be only terminated with ^C. This is true even for the newest mdadm built from git. "cat /proc/mdstat" blocks too. All mounted raids are working (at least ls <mountpoint> is), exept for one, md127 (the storage of backuppc). There ls is blocking and is not terminable by ^C. The raid structure is the following: md2, md3, m4 raid1 for swap, /boot, / md30 raid0 for short term storage md10, md11, md12, md13 raid0, built from 2x 2TB or 1TB + 3TB drives md127 raid5 built from md10, md11, md12, md13 I recently (some 12 hours ago) added md13 again and the system was rebuilding from a degraded state. The file system on md127 is xfs. All the physical rives are OK, at least according to smartmontools. Webmin 1.660 reports: CPU load averages 16.96 (1 min) 15.04 (5 mins) 12.67 (15 mins) CPU usage 0% user, 1% kernel, 99% IO, 0% idle Is there any way to diagnose the problem further? I'm reluctant to do a reboot.
