Hi,
How do I disable striping and debugging in a 1.6 Lustre file system that
I''ve created? Seems to me tunefs.lustre won''t do this.
I tried to format the disk and then re-run mkfs.lustre with
lov.stripe.count=0, but keep getting the following error:
[root@cfs2 ~]# mkfs.lustre --fsname=testfs --mdt --mgs /dev/hda8
Permanent disk data:
Target: testfs-MDTffff
Index: unassigned
Lustre FS: testfs
Mount type: ldiskfs
Flags: 0x75
(MDT MGS needs_index first_time update )
Persistent mount opts: errors=remount-ro,iopen_nopriv,user_xattr
Parameters:
checking for existing Lustre data
found Lustre data
mkfs.lustre FATAL: Device /dev/hda8 was previously formatted for lustre.
Use --reformat to reformat it, or tunefs.lustre to modify.
Here is how I formatted the disk:
[root@cfs2 ~]# mkfs.lustre --reformat --mdt --mgs /dev/hda8
Permanent disk data:
Target: lustre-MDTffff
Index: unassigned
Lustre FS: lustre
Mount type: ldiskfs
Flags: 0x75
(MDT MGS needs_index first_time update )
Persistent mount opts: errors=remount-ro,iopen_nopriv,user_xattr
Parameters:
device size = 2047MB
formatting backing filesystem ldiskfs on /dev/hda8
target name lustre-MDTffff
4k blocks 0
options -J size=80 -i 4096 -I 512 -q -O dir_index -F
mkfs_cmd = mkfs.ext2 -j -b 4096 -L lustre-MDTffff -J size=80 -i 4096 -I
