Problems with ext3
Hello, I converted one of my servers to ext3 and load average numbers went up. Now they are ~2-3 while on ext2 LA was <0.4. And I''m constantly seeing processes and kjournald in D state. vmstat confirms that. But even in such LA CPUs are ~99% idle. What can be wrong? RedHat 7.1 kernel 2.4.18-18.7.xsmp. SCSI cards: Compaq RAID array controller (cciss) and Q Logic ISP1020

File size differences
Hey, I have two identical machines setup with a RAID 5 array. One of them is used for failovers and data from the master is synced everyday using rsync to the failover machine. The data on this disks are usually intranet KB''s, DB''s etc.. The RAID 5 arrays are formatted using the default options i,e mkfs.ext3 /dev/Xda. The RAID controller is 3ware escalade and each disk

journal tuning
Hello, Is there some document about ext3 performance tuning and choosing the right type and size of journal? Except RedHat''s white paper. From what I read I understood that for typical operations data=ordered is prefered. For the cases when there are many writes not appending to files data=journal is the choice. And if I want to get the most performance or in case where program is

ext3 incompatability between linux 2.4/ppc and linux 2.6/x86
Hi, I''m using ext3 filesystems in embedded devices (storage is on 512Mb or 1Gb CF cards). A typical development cycle would see the filesystem created on the desktop PC running linux 2.4 (eg. RedHat 9). The CF card would be installed in the hardware and linux 2.4 (eg. Montavista Pro 3.1, on PPC) would boot from the CF. Recently I tried a linux 2.6 desktop (CentOS) for the same task

Crashed kernel System - fully (except kernel) updated RedHat 7.3. Filesystems - ext3 in default ordered mode. What could be the cause of the crash? Kernel update will solve the problem? Thanks, Mindaugas

Hello, Just became curious - is O_DIRECT already supported on ext3 or not yet? And a little bit offtopic :). Is that flag supported on some other filesystem other than ext2? Thanks, Mindaugas

How to hide .journal file
Hello, Maybe it''s already FAQ but how to hide .journal file on rootfs? I upgraded filesystems on one of my servers from ext2 to ext3 and everything went smoothly. I''d like to avoid booting from alternative media because server is in production. FS update done together with server''s kernel update. Thanks, Mindaugas

EXT3 and large directories
I have an ext3 filesystem that has several directories and each directory gets a large number of files inserted and then deleted over time. The filesystem is basically used as a temp store before files are processed. The issue is over time the directory scans get extremely slow even if the directories are empty. I have noticed the directories can range in size from 4k - 100M even when they are

repeated crashes
Hello, I''ve got a problem that is not solved after an e2fsck. What happens is that the kernel (vanilla 2.6.12) does this: journal_bmap: journal block not found at offset 1036 on hda6 Aborting journal on device hda6. ext3_abort called. The filesystem is mounted with errors=panic, so the system reboots. At boot-up an e2fsck is run on /dev/hda6. Sometimes it finds errors,

Slow backup and kernel upgrade issue.
I have a DL360 with dual 1266MHz processors, 2GB memory, and two 18.2 GB hard drives mirrored using the integrated controller. Partitions are formatted as ext3. I have noticed that the backup is up to 10 times slower than similar systems we have using ext2 instead of ext3. I am not utilizing any of the journaling capabilities of the filesystem. In addition, I have tried to upgrade the kernel

Errors on EXT3 on RHEL3, Can we use e2fsprogs 1.36?
SUMMARY We are getting many ``Free blocks count wrong for group'''' errors when running e2fsck on a 245-GB ext3 filesystem. This is when the file system is cleanly unmounted on a relatively quiet system to do a resize. From reading other messages here, my suspicion is that this is because we have e2fsprogs 1.32. Questions: * Should we use e2fsck/e2fsprogs 1.36 and will

All data "gone," lost+found is left.
So you know, I don''t know too much about file systems. Here is what I did: I have two linux boxes. the first box had many hardrives in it, but needed to be used in other ways. So I took 4 harddrives out of it and placed it in the other Linux box. I thought it would be able to read these right away. (maybe this was my mistake?) I could mount all of the drives in there. three of

Kernel panic in ext3:dx_probe, help needed
This may or may not be ext3 related but I am trying to find any pointers which might help me. I got a number of HP Proliant DL380 g5 with a P400 controller and also two qla2400 cards. The OS is RedHat EL4 U5 x86_64. Every time during reboot these systems panic after the last umount and I believe before the cciss driver is getting unloaded. The last messages I am able to see are: md: stopping

/var goes read-only
This is an issue that I have been having with one of our production servers for a couple of months, just out of no where /var goes to read only. There aren''t any errors that show up in /var/log/messages nor dmesg, I checked to make sure that the drives on error option is set to continue and there isn''t anything as far as I can tell wrong with the disks.

ext3 performance with hardware RAID5
I''m setting up a new fileserver. It has two RAID controllers, a PERC 3/DI providing mirrored system disks and a PERC 3/DC providing a 1TB RAID5 volume consisting of eight 144GB U160 drives. This will serve NFS, Samba and sftp clients for about 200 users. The logical drive was created with the following settings: RAID = 5 stripe size = 32kb write policy = wrback read
