Guys, one of our boxes just died with the following error: kernel panic - not syncing: fs/block_dev.c:396: spin_lock (fs/block_dev.c:c0361c0) already locked by fs/block_dev.c/287. The system's an LVS running CentOS 4.3: centos-release-4-3.2 kernel-2.6.9-34.EL ipvsadm-1.24-6 heartbeat-1.2.3.cvs.20050927-1.centos4 I note that there's a bug report filed related to CentOS 4.2: http://bugs...

This patch includes a fix to no longer list devices with 0 bytes of storage, such as removeable media devices with no media present.

Hi Jens, this series removes the revalidate_disk() function, which has been a really odd duck in the last years. The prime reason why most people use it is because it propagates a size change from the gendisk to the block_device structure. But it also calls into the rather ill defined ->revalidate_disk method which is rather useless for the callers. So this adds a new helper to just propagate the size, and cleans up all kinds of mess around this area. Follow on patches will eventuall kill of ->revalidate_disk e...

This one incorporates feedback from mburns and apevec to ensure that all multipath devices are excluded in the list of available drives. Only drives with an identified bus are included in the list now.

I have installed two CentOS 4.3 boxes with LVS (from http://mirror.centos.org/centos/4/csgfs/ ) but all boxes died withe this error frequently: kernel panic - not syncing: fs/block_dev.c:396: spin_lock (fs/block_dev.c:c0361c0) already locked by fs/block_dev.c/287. I have read from this thread http://threebit.net/mail-archive/centos/msg00243.html that this is an unsolved problem. So i have installed the kernel-2.6.9-39.EL from testing repo, but the box diedi with another error:...

Hi, We have file readahead to do asyn file read, but has no metadata readahead. For a list of files, their metadata is stored in fragmented disk space and metadata read is a sync operation, which impacts the efficiency of readahead much. The patches try to add meatadata readahead for btrfs. In btrfs, metadata is stored in btree_inode. Ideally, if we could hook the inode to a fd so we could use

The following patches introduce support for multipath and cciss devices to the ovirt-node and node-image. Comments are appreciated. These patches assume that the 3 patches (2 node, 1 node-image) from Joey are all incorporated. Mike

V1->V2: Check to see if our current ppos is >= i_size after a short DIO read, just in case it was actually a short read and we need to just return. This is similar to what already happens in the write case. If we have a short read while doing O_DIRECT, instead of just returning, fallthrough and try to read the rest via buffered IO. BTRFS needs this because if we encounter a compressed or
