For the record I've just tested linux- image-3.2.0-030200rc2-generic_3.2.0-030200rc2.201111151435 and the bug is still present. This is still on XenServer 5.6 SP2; I'll try to test on a XS 6 install later. (Lucid does work on both versions; the problem is only with Oneiric.)
Stefan: I hadn't spotted the capacity change discrepancy, but on my latest test with the above kernel I do get capacity change messages for all three disks: [ 0.492436] blkfront: xvda: barrier: enabled [ 0.495160] xvda: unknown partition table [ 0.496794] blkfront: xvdb: barrier: enabled [ 0.498990] xvdb: unknown partition table [ 0.499217] Setting capacity to 524288 [ 0.499225] xvda: detected capacity change from 0 to 268435456 [ 0.499911] blkfront: xvdc: barrier: enabled [ 0.501937] xvdc: unknown partition table [ 0.502127] Setting capacity to 12582912 [ 0.502136] xvdb: detected capacity change from 0 to 6442450944 [ 0.507102] Setting capacity to 1024000 [ 0.507117] xvdc: detected capacity change from 0 to 524288000 These disks are all XenServer's NFS-backed virtual disks. The bug does NOT occur if the root filesystem is on local storage. ** Summary changed: - Xen blkfront i/o errors prevent boot in domU + Xen blkfront i/o errors on NFS-backed disks prevent boot in domU -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/824089 Title: Xen blkfront i/o errors on NFS-backed disks prevent boot in domU To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/824089/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
