I have a large LV, about 6.5T, consisting of 4 physical drives of various sizes. The LV is formatted as ext4. There is no raid involved (hardware of software). After I first boot, if I try to write a large file (&gt;~ 80M) to this LV, the write hangs for about 1minute or more, then continues on at full speed and finishes successfully. Writes of small files don't show this delay. After that first write and delay, all subsequent writes to other large files proceed at full speed. I am currently running Fedora 17 64bit (kernel 3.8.4-102.fc17.x86_64) but have noticed this also in previous systems (both 64 and 32bit). With smaller file systems ( &lt; 1T ), there was a delay, but it was small, and it increased significantly as I increased the LV size. I have run e2fsck with the -D option (before attempting a write), which made no difference. Also, fwiw, I am mounting this with the default options.

I have ext4 all over the place on ~200 servers and never ran into such a problem. The filesystem capacity is 300 GB (19,6M inodes) with 196 GB (9,3M inodes) used. It's mounted 'defaults,noatime'. It sits on a hardware RAID array thru plain LVM slices. The RAID array is a RAID5 running on 5x SATA 500G disks, with a battery-backed (RAM) cache and write-back cache policy. To be precise, it's an Areca 1231. The hardware RAID array use 64kB stripes and I've configured the filesystem with 4kB blocks and stride=16. It also has 0 reserved blocks. In other works the fs was created with 'mkfs -t ext4 -E stride=16 -m 0 -L volname /dev/vgX/Y'. I'm attaching the mke2fs.conf for reference too. Everything is running with Debian Squeeze and its 2.6.32 kernel (amd64 flavour), on a 4 cores and 4 GB RAM server.

I found that it might also happen that journal is aborted but not re-mounted 2. Journal gets aborted but it might be possible to mount it in read-write mode. 3. Can we write some data on the partition where journal is aborted. Thanks in advance Regards Shubham </pre> shubham 2012-11-07T16:41:28 http://comments.gmane.org/gmane.comp.file-systems.ext3.user/4969 <pre>Hi All, This is my first post in this mailing list. I am a learner in this field. I have a query here : 1. If ext3 filesystem's journal got curropted then is it necessary thatfilesystem will be mounted read only ? either YES/NO, I want to know the reason also. (If I can get some links/document for this then it will be really useful) 2. Also I would like to know that how we can find root cause of ext3 corruption ? 3. In case we found root cause then how to fix and test the code. I think in this case regression would be required because file system can impact whole system. So , how to be sure about my fix . Please reply ..

For example, given a RAID 50 made up of two 3+1 RAID 5s striped together (so 8 disks total) with a 512k chunk size and 4k block size, the stride should be 128 (512 / 4) and the stripe-width should be 768 (stride * 6 data disks). These settings should work equally well whether the two RAID 5s are striped together or just appended one after the other via LVM. Is my reasoning correct?

This works fine except when there is a hard-link to the file being renamed to the target file. In this case the reading thread hits file not found errors (not always but often). This seems to break the sped for 'rename'.
