I'm not certain if I'm having the same trouble as you, but mdadm fell over pretty hard for me on 2.6.24-16-server, mdadm - v2.6.3 - 20th August 2007 when expanding 5x500GB -> 6x500GB. I lost all the data on the raid (oops).
Possibly this is a bug in sata_sil with lots of disk writes? 5 of the 6 disks were on siI 3512 based SATA cards (The other was an onboard mobo SATA port). Similarly, I can write to the disks individually fine, they check out okay with badblocks and smartctl. Did you get any weirdness in dmesg? I had a couple of odd things about the SATA link going down... so possibly unrelated. -- mdadm, Raid5 and XFS stuck in uninterruptable sleep https://bugs.launchpad.net/bugs/208551 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
