Jiri, any updates on this? Have you tested with latest kernels? Thanks. *** This bug has been marked as a duplicate of bug 8421 *** Hello Natalie, unfortunately I didn't test it with the latest kernels. My final step was to use a rc version (I'll post the exact number as soon as I will reach the server). With this kernel this problem was not present any more. But remaines the problem that after the disc is inserted back into the server it gets another /dev/sdX number and thus can't be smoothly added to the raid.

Distribution: OpenSUSE 10.1 Hardware Environment: Supermicro H8DCE motherboard (based on nVidia nForce Pro chipset) with two AMD Opterons 246 2x SATA harddrives WD1600JS inside hotplug SATA bays Problem Description: Hello, I observe a problem described bellow. I'm not sure if it's not related more to MD (RAID) then SATA. I'm running two SATA disks in a software (md) RAID1. If I extract a disk from RAID array, I would expect it should by instantly signed by RAID as faulty but a test shows something else. If I extract one HDD from RAID1 the kernel freezes after first request towards filesystem. If I insert the HDD back, kernel runs again and the MD RAID state remains unaffected (output of /proc/mdstat without any failure). After kernel revovery from the frozen state the syslog shows: Jun 8 13:03:48 helpdesk kernel: nv_sata: Secondary device removed Jun 8 13:04:18 helpdesk kernel: ata2: command 0xea timeout, stat 0xd0 host_stat 0x0 Jun 8 13:04:18 helpdesk kernel: ata2: translated ATA stat/err 0xd0/00 to SCSI SK/ASC/ASCQ 0xb/47/00 Jun 8 13:04:18 helpdesk kernel: ata2: status=0xd0 { Busy } Jun 8 13:04:18 helpdesk kernel: ATA: abnormal status 0xD0 on port 0xC007 Jun 8 13:04:18 helpdesk kernel: ATA: abnormal status 0xD0 on port 0xC007 Jun 8 13:04:18 helpdesk kernel: ATA: abnormal status 0xD0 on port 0xC007 Jun 8 13:04:37 helpdesk kernel: nv_sata: Secondary device added Jun 8 13:05:18 helpdesk kernel: ata2: command 0x35 timeout, stat 0x50 host_stat 0x21 If I extract one HDD as above but wait for long enough time while the kernel is frozen then after two minutes some timeout occures. Then the extracted HDD is kicked out from the RAID and kernel runs again.
