Feature changed by: Maximilian Maher (maxmaher) Feature #305691, revision 76 Title: Support ext4 as installation option openSUSE-11.2: Done Priority Requester: Mandatory Projectmanager: Mandatory Requested by: Stephan Binner (beineri) Description: Next openSUSE release should at least support to use (versus "default to") ext4 as file system. Test Case: - Install Opensuse 11.2 and choose ext4 as Filesystem + * Install Opensuse 11.2 and choose ext4 as Filesystem for root / Discussion: #1: Piotrek Juzwiak (benderbendingrodriguez) (2009-01-18 03:29:23) I think there will be an option to that naturally as openSUSE 11.1 will use the newer kernel with stabilized ext4 tree. All the tools for it are already there and GRUB also supports it. It's not necessary to vote for this feature as it will naturally be there. #9: Martin Zeltin (queenz) (2009-02-10 18:34:03) (reply to #1) I really hope that Ext4 will be the default File System for openSuSE 11.2 It is really good. #10: Stephan Kulow (coolo) (2009-02-18 17:01:17) (reply to #9) did you testing and comparisions yourself? or is that hearsay? #2: Piotrek Juzwiak (benderbendingrodriguez) (2009-01-18 03:29:43) Sorry meant 11.2 #3: Claus Rebler (zunami) (2009-01-18 17:55:32) yeah that is a good idea but @ version 11.2 #4: Jan Engelhardt (jengelh) (2009-01-19 09:50:29) XFS has had many features of ext4 for years already (and is currently also supported by openSUSE and grub). #5: Jan Engelhardt (jengelh) (2009-01-19 09:52:16) (reply to #4) But yeah, support would be great. At the same time, btrfs could be added as an experimental selection. #6: Piotrek Juzwiak (benderbendingrodriguez) (2009-01-23 22:22:23) The problem with XFS is that it's no longer maintained. Second is that it gets fragmented heavily. #7: Grozdan Nikolov (microchip8) (2009-01-28 14:59:00) (reply to #6) what do you mean by no longer maintained? Only in openSUSE or in general? If in general, I highly doubt XFS is no longer maintained as it's still actively under development (check out xfs mailing list). And how does XFS gets fragmented heavily? Out of all file systems for Linux so far, it offers the least amount of fragmentation. I do not use XFS as main file system on my rigs because I've had a lot of problems with it, mostly messing up things after power outage or hard reboots #8: Stephan Kulow (coolo) (2009-01-28 15:07:58) (reply to #7) could you please discuss different file systems elsewhere? This is not the correct forum. #14: Arvin Schnell (aschnell) (2009-05-05 10:55:10) Added jreidinger and juhliarik as developers since YaST bootloader also needs support. #15: Jozef Uhliarik (juhliarik) (2009-05-20 14:50:43) yast2-bootloader 2.18.8 includes support check for ext4. If /boot direcotry si on partition with ext4 filesystem yast2-bootloader shows warning message. There is necessary to create separete /boot partition with ext2/3. IMHO the feature is done for yast2-bootloader and also for perl-Bootloader #16: Stephan Kulow (coolo) (2009-05-20 14:59:26) (reply to #15) why does it do that? The patch for fate#305162 is doing what it should on my laptop. #18: Stephan Kleine (bitshuffler) (2009-05-25 16:40:35) Since the now removed comment once again emphasizes that one should never ever use ext4 for /boot for some unknown reason could anyone please explain why this should be such a problem and or poste some links / pointers to more information backing this up? I'm just seriously wondering since I'm using ext4 for /boot on Arch since they released a kernel where it wasn't marked experimental anymore and never experienced any problem. Thanks a lot in advance. #21: Jozef Uhliarik (juhliarik) (2009-05-27 15:40:29) It seems that it will be nice discussion where I am the bad guy who is against booting from ext4 and who block nice perfect and cool feature. ; -) but... the truth is out there. Adding Torsten Duwe to feature. Torsten please write there any nice comment about GRUB and ext4. I ma sure that you are the best person who can respond for all questions in the feature. #22: Torsten Duwe (duwe) (2009-05-27 17:48:03) (reply to #21) Let me get 2 things straight: 1) "boot" and "root" are different things 2) I'm not against ext4. Anyone in this group please speak up that he will investigate and fix ext4-related boot problems bacause frankly I do not have the time any more. #23: Torsten Duwe (duwe) (2009-05-27 17:52:21) (reply to #21) Reading files from ext4 currently is possible from grub, but I strongly vote against making ext4 the default file system to boot from, as long as my previous Issue #2 is unresolved. #24: Bergwolf Paine (bergwolf) (2009-06-03 05:51:22) (reply to #23) Hi, Torsten I am the GSOC student writing grub4ext4 patch last year. I'm running x64 opensuse on ext4 on my laptop. And I boot from ext4 partitions without any problem. The migration only needs a new initramfs and some small e2fsck scipt change (in opensuse's script there was an option that upstream e2fsck doesn't understand, iirc, because my migration was almost half a year ago). #25: Bergwolf Paine (bergwolf) (2009-06-03 08:53:15) (reply to #23) And I don't mind to be added to the cc list of any boot-kernel-on-ext4 related problems. I am willing to help to fix them. #26: Jiri Benc (jbenc) (2009-06-08 13:18:19) (reply to #25) Thanks, Bergwolf! As it seems all of the mentioned issues are resolved now, could we please have the proper support for ext4 in YaST? #27: Jozef Uhliarik (juhliarik) (2009-06-08 14:57:27) (reply to #26) Yes of course. Please just ignore the warning message about using of ext4 from yast2-bootloader. I will delete it later. #28: T. J. Brumfield (enderandrew) (2009-06-13 20:52:12) Shouldn't this feature be marked as completed? Hasn't EXT4 support been added to 11.2? -- openSUSE Feature: https://features.opensuse.org/305691
