ext4 reflections

I tired ext4 about a year ago. It was doing fine till I got a power outage and it fried my filesystem.
Now am using xfs.

I've been using it for about a year now, I had one problem in the early days where it seemed one of my partitions got corrupted but I managed to recover all my data. The main advantage I found is that system booting flies compared to when I had ext3, or even xfs.

EXT4 always caused me to have some corrupt files in /etc/ to the point where my /etc/rc.conf was blank. This meant I had to put in a rescue knoppix disc, edit the file and paste the text that I found on the net. Just before anyone screams virus, it wasn't, and the problem is highlighted at the sites:
1.http://ubuntuforums.org/archive/index.php/t-1040199.html
2.http://bbs.archlinux.org/viewtopic.php?id=74362

I use ext3 now and everything has been doing great so far.

I'm using ext4 on an old laptop and I regularly have disk check errors during boot (which require a manual check before rebooting). At first I thought it was due to failed suspend to RAM attempts or turning off the system improperly, but it happens under regular use. I don't know enough to conclude if it's the filesystem or a bad hard drive, but it definitely doesn't inspire confidence.

Combination of btrfs and Ext4 here. No direct issues with either FS, but since 2.6.32, I've been unable to mount AUFS on either FS with write barriers enabled.

i've only barely used ext4 but i will probably be using it more for the larger filesystems that i run. the old ext3 limit (if i remember right was a bit of a pain) being able to create 30tb+ sized systems would be nice. so far i use xfs for filesystems bigger than 4tb.

I used to use ext4 but migrated to reiserfs3 when I was noticing faster delete-times and read-writes (just from observation) on my reiserfs partition. After a while all my partitions became reiserfs and I never looked back. Nothing really wrong with ext4, it would probably be my second choice, but even the fsck's are faster on my laptop and I have some pretty big video files on here. Just my experience/opinion, blah blah.

I've been using Ext4 for a while now too. I've noticed no change from Ext3.

I moved / and /var to ext4 from jfs. /home is still jfs

There is no difference in speed that I can perceive, but a stopwatch says otherwise. ext4 is very slightly faster (with writeback and nobarrier). If I knew what performance improvements I would get before doing it, I wouldn't have bothered.

As an aside, fsck'ing after an unclean shutdown is faster in jfs than in ext4.

I've never experienced any data loss in either jfs or ext4, although I can't say the same for reiserfs or fat32.

If I was reinstalling I'd use jfs again, just because it's reputation for soundness is much more established than ext4's.

I use ext4 on all of my linux partitions (with the exception of my home directory partition), and I've had no problems with it whatsoever. It's totally stable and is even a bit faster than ext3.

Agreed.
I prefer and mostly use JFS. It's never let me down.
A nice ReiserFS /var really makes pacman zip, though.

ext4 + using mysql with amarok1.4 makes me want to cry, particularly when editing a large number of files, say 1,000 tracks. In this specific case, ext3 flew through them. I guess I could disable barriers in ext4, but that would risk data corruption :-\

Ranguvar · 2010-06-04 01:59:10

I've never had a single problem with ext4 (probably because during the whole file corruption debacle I switched to nodelalloc), and I use it for all my partitions.
It's well supported, resizes in any way you might care for, in general a solid filesystem -- and when it comes to filesystems, solid is desirable.
I'm not really feeling a need for speed lately (I run with barrier=1), but ext4 is no slouch, either.
In general satisfied, except I'd love on-the-fly compression a la Reiser4. That can save a ton of space in some circumstances, and even _improve_ speed in a lot of cases.

kokoko3k · 2010-06-05 07:19:38

isn't barrier=1 the default mount option?
Btw, i explicitely mount all with barrier=0 to gain speed.
Maybe i'm lucky, but i never had a problem with corruption/blank files (i use it on 2 desktops and 1 laptop), even after hard reboot
I just make sure to issue "sync" after editing critical files.

Been using ext4 on both partitions I have since I started with Arch Linux on April 1st. No problems so far, and everything works nicely.

dyscoria · 2010-06-05 08:09:17

ext4 gave me a one second improvement in bootspeed compared to ext3..... now that's what i call speed.
