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 (isp_mod).

RE:How to decide mode and journal size?
Hi.
I am using a large storage which is ext2 file system of 1T byte.
It has many file types, doc, mail data, zip, etc. It doesn't have
a database file. I want to change the file system from ext2 to
ext3. It also can't divide to any partitions.
How to decide journal mode and journal size?
Please advice to me.
Recommend a journal mode. (orderd or journal)

ext3 + loop + journaling
[ If this is explained somewhere else (HOWTO or FAQ), please give me a
pointer. ]
Is there any way to mix loop-device (and in particular) loop-AES and ext3
together in data journaling mode?
Ie.
bottom -> to -> top
ext3 - loop-AES - ext3
raw - loop-AES - ext3
Or am I shooting myself to leg, I am?
BR, Jani

ext3 on debian-HPPA Linux?
Right now I'm building a 2.4.17 kernel on an HPPA Linux system. The
kernel it ships with supports ext2 only. Has anybody tried ext3 on HPPA?

ext3 data
I am using kernel 2.4 and ext3 fs on all partitions.
I recently suffered a power outage while working on
some documents. Some of them had previously been
saved other had not. In either case none of the new
data was restored. I am also finding other strange
disapearrances like bookmarks and panel applets.
My understanding of the ext3 fs is that these
documents should have been restored

drbd + ext3 + interbase + data lost
Hello All,
Yesterday, one of our customer's cluster(2 box) server goes down after a

Now, I'm with one of the disks (the other was used to rebuild the

from the disk.

postfix and ext3
I am running postfix on RH machine. decided to upgrade one of my machines from 7.1 to 7.2 - performance drop of 75
percent !!!!!
moved back to ext2(remount partition as ext2) - performance is back.
on the 7.1 upgraded to ext3 (only the disks), rebooted - performance
drop of 70 percent...
used a 2.4.17 kernel compiled by myself - a little faster then the
last RH kernel, but still runs at third

Major problems
I am having major problems on one of my file-servers. I have the root
filesystem on an Ext3 software RAID 1 between four SCSI drives. It had been
running for about two months without problems, but today I found it was
having some trouble with unlinked inodes and I/O errors on certain files. I
took it down to single-user mode, and ran fsck on it. That operation mixed
up files like /etc/hosts with

Howto recovering an ext3 fs
Dear ext3 hackers,
I'm running a RH 7.2 system with kernel 2.4.18 an a ext3 fs.
Yesterday night this machine, which is being tested with a Proxy server
(Squid), was accidentally power off (electrical outage). Now, when the
system is booted, I have a ext2 'read only' fs; fsck doesn't find any kind
of problem (automatic or manually executed: fsck -t ext3 /dev/sdb1). The

slowdown and reiserfs
hi
i got 2 questions and maybe someone could shed some light:
a) i'm using kernel 2.4.17 and use ext3 in it. is it possible that the
whole system is slower than with ext2? i switched back to ext2 (great
feature!!!) and the system's response seemed somewhat better.
should/could there be such a effect as double writing of journaled data?
i didnt activate debugging (jbd).
b) is reiserfs

Redhat 7.3 as CentOS 5 domU
Hello,
What is the simpliest way to run Redhat 7.3 server as CentOS 5 domU?
I see that Xen emulates Intel PIIX ATA controller for HVM domUs but
latest kernel of Redhat 7.3 (2.4.20-20.7smp) has no ata_piix kernel
module yet. Is it possible to download it somewhere or there is
another way? :)
And I'd like to avoid reinstalling them with the new OS. Preferably
they'd just die their

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.

Painfully slow NetApp with databas
Hello,
We have long running problem with NetApp filers. When we connect
server to the filer sequential read performance is ~70MB/s. But once
we run database on the server seq read performance drops to ~11MB/s.
That's happening with two servers. One is running Oracle another -
MySQL. During speed tests database load is very light (less than 1MB/s
of reads and writes). During the tests NetApp

Xen virtual machines management
Hello,
What do you use to manage virtual Xen machines? Nothing complex
though preferably. :)
I've already converted some servers for a Xen dom0 and starting to
loose the picture - which VM runs where and how much resources left on
each server.

ext3 on Linux software RAID1
Everyone,
We just had a pretty bad crash on one of production boxes and the ext2
filesystem on the data partition of our box had some major filesystem
corruption. Needless to say, I am now looking into converting the
filesystem to ext3 and I have some questions regarding ext3 and Linux
software RAID.
I have read that previously there were some issues running ext3 on a
software raid device

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?

O_DIRECT
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,
