Subject: Can't mount after mkfs -b 8192
Date: Thu, 03 Jun 2004 23:31:57 +0100 [thread overview]
Message-ID: <40BFA6DD.6000904@dgreaves.com> (raw)
Hi
First - thanks Guy - I've setup using 1 big partitions and I'll deal
with monitoring as you suggest.
(BTW, are patches to mdadm recvd well? If so I'll take a look -
especially at the state=spare message when rebuilding.)
Anyway, I now have an lvm2 on top and wanted a reiserfs (actually, since
I'm ex-sgi I wanted xfs - but it doesn't shrink :( ) and I'm having odd
behaviour. (Also, I posted to the reiser list but thinking about it,
raid makes as much sense...)
So, environment:
Kernel 2.6.6
progsreiserfs 0.3.0.4-3
Summary:
I have a raid5 array in an LVM2 VG with a 600Gb LV defined.
If I make a reiserfs with a block size of 8192 it won't mount.
The following commands were issued consecutively:
cu:~# mkfs -treiserfs /dev/video_vg/video_lv
All data on /dev/video_vg/video_lv will be lost. Do you really want to
create reiser filesystem (v3.6) (y/n) y
Creating reiser filesystem (v3.6) with standard journal on
/dev/video_vg/video_lv
initializing skiped area: done
initializing journal: done
syncing...done
cu:~# mount /dev/video_vg/video_lv /huge
cu:~# df -k
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/hda2 19283776 697988 18585788 4% /

/dev/mapper/video_vg-video_lv
629126396 32840 629093556 1% /huge
cu:~# umount /huge
cu:~# mkfs -treiserfs -b 8192 /dev/video_vg/video_lv
All data on /dev/video_vg/video_lv will be lost. Do you really want to
create reiser filesystem (v3.6) (y/n) y
Creating reiser filesystem (v3.6) with standard journal on
/dev/video_vg/video_lv
initializing skiped area: done
initializing journal: done
syncing...done
cu:~# mount /dev/video_vg/video_lv /huge
mount: wrong fs type, bad option, bad superblock on /dev/video_vg/video_lv,
or too many mounted file systems
dmesg now shows:
sh-2011: read_super_block: can't find a reiserfs filesystem on (dev
dm-0, block 16, size 4096)
sh-2021: reiserfs_fill_super: can not find reiserfs on dm-0
any suggestions.
Nb I'll be storing 2-5Gb video files - hence the large blocksize.
David
