Limited write bandwidth from ext3
We are running a benchmark that does single threaded 512 KB writes to a LUN on a CLARiiON storage array. The dual Xeon host (Dell 2650) with 4 GB of memory runs RHEL 4U3 We measured the write bandwidth for writes to the block device corresponding to the lun (e.g. /dev/sdb), a file in an ext2 filesystem and to a file in an ext3 file system. Write b/w for 512 KB writes Block device 312 MBps Ext2

BUG at fs/buffer.c:2933 during umount
Hi, I could not find this anywhere else reported, so here we go: creating a new btrfs filesystem (btrfs-progs-unstable from git) and mounting it succeeds, unmounting however fails with the kernel messages attached to this mail. After that, I can still read and write to the btrfs mount, but e.g. /bin/sync never finishes, sysrq-s never reports "Sync complete". I''m using a

Loop device performance
Hello, I have a production script that do read operations to a lot of small files. I read that one can gain performance boost with small files by using a loop device on top of Lustre. So a created 500 GB file striped across all of my OSTs(which are 8). I formatted the file with ext2 fs, and mounted it on a client. Just for the sake of testing a simple bash script finds all files with a given file

EXT2 vs. EXT3: mount w/sync or fdatasync
My application always needs to sync file data after writing. I don't want anything handing around in the kernel buffers. I am wondering what is the best method to accomplish this. 1. Do I use EXT2 and use fdatasync() or fsync()? 2. Do I use EXT2 and mount with the "sync" option? 3. Do I use EXT2 and use the O_DIRECT flag on open()? 4. Do I use EXT3 in full journaled mode,

a comparison of ext3, jfs, and xfs on hardware raid
I'm setting up a new file server and I just can't seem to get the expected performance from ext3. Unfortunately I'm stuck with ext3 due to my use of Lustre. So I'm hoping you dear readers will send me some tips for increasing ext3 performance. The system is using an Areca hardware raid controller with 5 7200RPM SATA disks. The RAID controller has 128MB of cache and the disks

I've backported all of the bugfixes to the 2.5 dxdir/htree patches to 2.4, and have created a new set of patches for Linux 2.4.21rc5.

I've done *very* light testing, and things seem to work, but I'm now

ext3 filesystems larger than 8TB
Greetings. I am trying to create a 10TB (approx) ext3 filesystem. I am able to successfully create the partition using parted, but when I try to use mkfs.ext3, I get an error stating there is an 8TB limit for ext3 filesystems. I looked at the specs for 5 on the "upstream" vendor's website, and they indicate that there is a 16TB limit on ext3. Has anyone been able to create

16TB ext3 mainstream - when?
Are we likely to see patches to allow 16TB ext3 in the mainstream kernel any time soon? I am working with a storage box that has 16x750GB drives RAID5-ed together to create a potential 10.5TB of potential storage. But because ext3 is limited to 8TB I am forced to split into 2 smaller ext3 filesystems which is really cumbersome for my app. Any ideas anybody?

chattr +T not implemented?
We run a third party application that creates an inordinate amount of subdirectories in a single directory. To speed up I/O, I wanted to set the T attribute on the directory that will hold the subdirectories. The "chattr +T /usr/local/lepus-bb/a-0607" command returns status 0, but when I verify the setting, the attribute isn't there: # lsattr -d /usr/local/lepus-bb/a-0607
