Changes to GFS 6.1 for RHEL4 U2
This release supports iSCSI and multipath iSCSI. That is, device mapper
multipath (dm-multipath) can use iSCSI.
This release prevents the activation of snapshots in a clustered volume
group.
Important Notes
Multipath GNBD is not available with this and previous releases of
Red Hat GFS 6.1. That is, device mapper multipath (dm-multipath)
cannot use GNBD. GNBD without multipath *is* available.
Bugs Fixed in the Release
o 160525 -- GFS fsck [gfs_fsck] not handling extended attributes correctly
o 160835 -- fsck [gfs_fsck] erroneously reporting bitmap corruption when
converting bits from free_metadata -> free_data
o 162709 -- gfs_fsck fails to complete, can't mount the device
o 161808 -- Nodes don't wait for first mounter to finish recovery [This could
potentially allow a second node to mount a GFS file system
while the journal was being replayed.]
o 164324 -- gfs oops in gfs_wipe_buffers [This could allow depend_sync_old
to corrupt the resource group descriptor structure if it took
too long to sync dependent inodes back to disk.]
o 166701 -- Kernel panic with NFS traffic being moved between nodes using
service IP address [This caused a kernel panic in rare
cases when using NFS on top of GFS.]
