Hi,
I''m trying to bring up Lustre 1.6.0.1 on RHEL4 U4 using the downloaded
rpms, but the mkfs.lustre command keeps failing (see below). Evidently
it cannot find ldiskfs (the /dev/hdc1 shows up in fdisk as a valid Linux
83 partition). The manual/archives don''t seem to have much on this --
any thoughts?
Thanks in advance,
Ed Nadolski
[root@mojave ~]# mkfs.lustre --fsname spfs --mdt --mgs /dev/hdc1
Permanent disk data:
Target: spfs-MDTffff
Index: unassigned
Lustre FS: spfs
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: not found
device size = 980MB
formatting backing filesystem ldiskfs on /dev/hdc1
target name spfs-MDTffff
4k blocks 0
options -i 4096 -I 512 -q -O dir_index -F
mkfs_cmd = mkfs.ext2 -j -b 4096 -L spfs-MDTffff -i 4096 -I 512 -q -O
dir_index -F /dev/hdc1
mkfs.lustre: Unable to mount /dev/hdc1: No such device
Is the ldiskfs module available?
mkfs.lustre FATAL: failed to write local files
mkfs.lustre: exiting with 19 (No such device)

> Does "modprobe ldiskfs" work?No, tho I only see the .ko files under /lib/modules: [root@mojave]# modprobe ldiskfs FATAL: Module ldiskfs not found. [root@mojave]# find / | grep ldiskfs /lib/modules/2.6.9-42.0.10.EL_lustre-1.6.0.1smp/kernel/fs/lustre/ldiskfs .ko /lib/modules/2.6.9-42.0.10.EL_lustre-1.6.0.1smp/kernel/fs/lustre/fsfilt_ ldiskfs.ko FWIW, e2fsprogs, perl, and /etc/modprobe.conf are set up as per the manual. Are there any other requirements/steps (esp. for RHEL4u4)?

Yep, that seems to be working now -- thanks!
