 Posted: Wed May 23, 2007 11:11 am Post subject: ext4 - unsupported features! kernel panic! |
 |
|
hey ho, sorry for double posting this!
After installing vipernicus' net-fs/nfs-utils-1.0.12-r3, and the light4 kernel, everything worked. For weeks
As I updated my PC yesterday, portage installed viper2 and e2fsprogs-1.40_pre20070411. and BAM everything broke 
Kernel panics after the each reboot (or shutdown), even with the old light4 kernel. I had to use a the partedmagic-CD (ext4 support) to mount the partition, reboot, then finally the kernel booted init. Now when init started fsck.ext4dev, it complained about "unsupported features"!!!
So I'm kinda scared to reboot again, I might do a full backup first.
Is this problem caused by a change in the ext4 driver, or just e2fsprogs (you seem to have them removed from your overlay!!), or both?
Thanks!
edit: what about delalloc now? I dont think the kernel on the partedmagic-CD supports it, but does mine? Where's the benefit?
edit2: I think my problem is related to the delalloc I had in fstab once, but not it seems missing from e2fsprogs. How can I revert the allocation stuff back to normal? |

Yeah delalloc is a bit broken, don't use it.
It's supposed to increase performance because data is held in the cache as long as possible and it's written in optimized order on the disc.
Try mounting your discs with "nodelalloc". |

kay, trying it next time I reboot.
Is there a way to make the kernel more fault-tolerant?
I mean it always panics when booting, but when I mount it with the livecd, it only says that some orphan inodes were deleted and mounts the filesystem cleanly afterwards...
seems kinda lame for a kernel not being able to delete some inodes, dont you think? |

what do you expect for using not on a beta filesystem, but a heavily dev'ed one at that. IF there is a bug in the kernel driver for the filesystem of cause the kernel will panic.
I do believe you were warned abt using this filesystem

1) Yes, stop using delalloc, I did that few days ago also. Time will come when it would be more stable.
2) block the e2fsutils-1.40 because there is no support for ext4, and emerge the one you use before. (me use 1.39-r2 in overlay patched by someone on this forum)
I had the same problem, so I booted to livecd and edit fstab not to fsck on boot "0 1" -> "0 0" mainly on root partition (best for evry u use ext4dev), till you dont emerge the correct e2fsprogs

I added nodelalloc to /etc/fstab.
But vipernicus' overlay doesn't have e2fsprogs any more (apart from being offline right now), and because I synched, I lost them as well. Are you sure my version doesn't support ext4? Where could I get a good one?

okay, I didnt reboot yet, but used mount -o remount, and this is what I got:
| Code: | keinstein ~ # mount | grep ext4
/dev/hda6 on / type ext4dev (rw,noatime,nodelalloc,extents)
keinstein ~ # fsck -n /dev/hda6
fsck 1.40-WIP (7-Apr-2007)
e2fsck 1.40-WIP (7-Apr-2007)
Warning! /dev/hda6 is mounted.
fsck.ext4dev: Filesystem has unsupported feature(s) while trying to open /dev/hda6
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>

okay, I finally rebooted, _and_ have a new kernel, aparently which has V2 of the ext4 drivers:
| Code: | veit@keinstein ~ $ uname -a
Linux keinstein 2.6.21-kamikaze3 #1 PREEMPT Thu May 24 01:57:56 Local time zone must be set--see i686 Mobile Intel(R) Pentium(R) 4 - M CPU 2.20GHz GenuineIntel GNU/Linux |
works good, kernel doesn't panic, fsck still complains about unsupported features, despite nodelalloc in fstab. I'm too lazy to compile e2fsprogs myself, I'm gona wait till someone writes an ebuild and just ignore the messages.
thanks everyone
edit: I fixed the timezone  |

okay, now it doesn't work any more. same kernel. I only added the extendet RTC support, but I dont see how that matters...
DAMNIT!
vieprnicus, what about e2fsprogs? |

| I don't understand, why don't you just reformat the partition? |

| du you mean reformat as other filesystem or just to get rid of the "unsupported features" stuff? |

Whatever stops the kernel from panicking.  |
