ocfs2 will become read-only if we try to read the bytes which pass the end of i_size. This can be easily reproduced by following steps: 1. mkfs a ocfs2 volume with bs=4k cs=4k and nosparse. 2. create a small file(say less than 100 bytes) and we will create the file which is allocated 1 cluster. 3. read 8196 bytes from the kernel using O_DIRECT which exceeds the limit. 4. The ocfs2 volume

Hi all! Several times now I have seen the following: fsck-ing the ext3 fs I get hundreds (if not thousands) of messages: Indoe NNNN, i_blocks is K, should be (K-8). FIXED: Interestingly the difference is *always* *always* *always* 8. Can someone explain me what was going on? Why this? Thanks a lot and all the best Norbert

Hi: I''ve met an ext4 Bug in dom0 kernel 2.6.32.36. (See kernel stack below) 32.36 kernel commit: http://git.kernel.org/?p=linux/kernel/git/jeremy/xen.git;a=commit;h=ae333e97552c81ab10395ad1ffc6d6daaadb144a The bug only show up in our cluster environments which includes 300 physical machines, one server will run into this bug per day. Running ontop of every server, there are about 30

/an ocfs2 bug: a truncate races with ocfs2_get_block(...,0). 1) 'dd' is doing a truncate, clearing the page cache and reset inode size./ /2) between clearing page cache and resizing inode, a read comes and create a / /new page and insert it to page cache./ /3) the read(from `cat`) set buffer head in the new page as mapped but doesn't increase / /ip_mmu_private in ocfs2_get_block()

Hi, I did some more in-depth testing of OCFS2 quota code, especially with ECC feature enabled and spotted some problems. First four patches fix them. I need the fifth patch to be able to mount OCFS2 filesystem with 2.6.31-rc3. The sixth patch fixes a potential problem when quota syncing interval is updated while the cluster is running (which is not possible currently). Joel, could you please

Hi, Michael I have met ext4 error when using vhost_scsi on arm64 platform, and suspect it is vhost_scsi issue. Ext4 error when testing virtio_scsi & vhost_scsi No issue: 1. virtio_scsi, ext4 2. vhost_scsi & virtio_scsi, ext2 3. Instead of vhost, also tried loopback and no problem. Using loopback, host can use the new block device, while vhost is used by guest (qemu).

Hi Linus, Here are some 2.6.20 fixes for ocfs2. The patch by Zhen Wei isn't really a fix, but a very small amount of support for a feature which is mostly implemented in ocfs2-tools. Considering it's just a single attribute export via configfs, I'd say it's pretty safe to merge. Please pull from 'upstream-linus' branch of

From: Nicholas Bellinger <nab at linux-iscsi.org> This patch changes virtio-scsi to use a new virtio_driver->scan() callback so that scsi_scan_host() can be properly invoked once virtio_dev_probe() has set add_status(dev, VIRTIO_CONFIG_S_DRIVER_OK) to signal active virtio-ring operation, instead of from within virtscsi_probe(). This fixes a bug where SCSI LUN scanning for both
