ext4 and extremely slow filesystem traversal
Hello list, I have troubles with the daily backup of a modest filesystem which tends to take more that 10 hours. 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

Calculating volume size from superblock
Another simple question. How do I calculate the size of the volume from the superblock? Do I just use the two fields: u_int32_t s_blocksize_bits; /* Blocksize for this fs */ u_int32_t s_clustersize_bits; /* Clustersize for this fs */ What is the formula to use? Thanks, John

[BUG?] probable underflow on file date on ext2/3 filesystems
Hi guys, a user at Gentoo Bugzilla, reported that he archives files with a artificial timestamp of 1970-01-01 on an ext3 partition on his amd64 box. After remounting that partition, the file date becomes 2106-02-07. I confirmed this bug and also tested it on several other partitions (xfs, reiserfs) and they don't have this problem, just ext2 and ext3 have it. This problem also

Can ext2 or ext3 filesystem manage sparse files? And so, in which way? Does it use extents? Thanks in advance. Daniele

Ext3 performance vs. Ext2 for synchronous I/O
We are testing Red Hat Advanced Server 2.1. I have a simple benchmark program that issues synchronous writes/reads to a file. When I ran it on a file system that was created by default as ext2, the elapsed time was about 5 seconds. After using tune2fs to convert the file system to ext3, the same run took about 10 seconds. I've tried all three of the journaling modes and it doesn't seem to

ext2->ext3 empty file creation
Hello, I am using kernel version 2.4.7-10 I upgraded one of the ext2 partition to ext3. the partitions are nearly empty. I ran a program to create empty files, having names in lexicographical order. The time taken to create empty files (100 .. 100000) is same on an ext2 partition and a ext3 partition. Can anyone pls. tell me why there is no difference in the time taken. Is the htree algo.

ext3 to ext2 conversion causes kernel panic
Hi, I try to convert my RedHat 7.3. partitions from ext3 to ext2. I have found a thread dealing with this issue. Thus: "tune2fs -O ^has_journal /dev/foo" and "e2fsck /dev/foo" will do the magic! This works fine for "/boot" but when I try to convert "/" my kernel panics? The kernel panics message appears shortly after the attempt to startup kjournald. How

Caveats to mounting ext3 as ext2?
I have a partition that is formatted as ext3 however, due to apparent performance issues (not sure if they are related to journaling - data=ordered, BTW) I have mounted this file system as ext2. The file system was clean when it was shutdown, and has been cleanly mounted as ext2, and I currently have no problems with the partition. My question is, is there any harm in mounting this partition as

Converting ext3 to ext2
According to this: http://www.redhat.com/support/wpapers/redhat/ext3/why.html ext3 is forward and backward compatible with ext2... Any user who wishes to un-journal a file system can do so easily... I am assuming un-journalling is the equivalent of converting it to ext2. How do you do this? I haven't been able to find anything. The reason I want to do this is so I can modify my
