which filesystem
hello i have and external USB hard-drive size 2TB, mounted as ext4. (ubuntu 10.10 amd64) every time there is a power failure. i need to do a manual fsck on this disk. and this takes around an hour ... i am looking to replace the ext4 file system with something better: 1. stable 2. more resilient to power failures 3. short fsck time 4, supported out of the box (i may want to mount this external disk on other computers with other linux distros e.g. centos). what can you recommend ? thanks, erez. ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

That's odd. At work I've got a number of Fedora 17 machines w/ ext4, (with our w/o software RAID) and a *very* flaky power network. As a result, from time to time one of our el-cheapo UPS' dies and the machines forcefully powers down. Thus far, I've only seen ext4 goes into full fsck once or twice. ... Have you checked the drive's ext4 settings? Maybe Ubuntu installer was too paranoid? - Gilboa ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

I have a 2 TB disk with ext3, and I don't have anything close to the 1 hour boots you report (even one minute looks excessive). Both ext3 and ext4 are journalling filesystems, meaning that after power failures, only a relatively small journal of the last modifications needs to be replayed, rather than going through the entire disk. Is it possible your filesystem for some reason has journalling disabled, or improperly configured? Try tune2fs -l on your filesystem and look for suspicious parameters. Look at Filesystem features and verify there is has_journal. See that it doesn't force a full fsck every time (Maximum mount count can very well be -1 and check interval 0). -- Nadav Har'El|Saturday, Aug 11 2012, 24 Av 5772 n...@math.technion.ac.il |- Phone +972-523-790466, ICQ 13349191 |This signature was intentionally left http://nadav.harel.org.il |boring. ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

From a quick search (using e.g. [2] and [3]) I got the following. Any comments and fixes before I submit it? I have seen that cyanogenmod also has a similar list. Do you think they are separated - or cyanogenmod are pulling data from freedesktop? I think that cyanogenmod's list will be more correct, or at least tested.
