[Lustre-discuss] Help with lustre 1.6.4

[Ali Algarrous]

My name is Ali Algarrous and I'm doing a research about Lustre file
systesm.

I'm running Debian on my machine and after a long time I was able to
install Lustre on my machine. I was able to format devices and mount
clients and servers easily but I had to reinstall the OS. So I started
the process of installing Lustre again and this time it was really
easy.

However, I came across another problem.  When i'm running this
command:  mkfs.lustre --fsname datafs --mdt --mgs /dev/sda3

I get the following error messgae:
______________________________________________________________________
gog:~# mkfs.lustre --fsname spfs --mdt --mgs /dev/sda3

 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: mdt.group_upcall=/usr/sbin/l_getgroups


mkfs.lustre FATAL: loop device requires a --device-size= param

mkfs.lustre FATAL: Loop device setup for /dev/sda3 failed: Invalid
argument
mkfs.lustre: exiting with 22 (Invalid argument)
_______________________________________________________________________
And then when i specified the size of the disk by putting --device-
size=40371345 I started to get the following error:
____________________________________________________________________
gog:/home/algarra# mkfs.lustre --fsname lustrefs --mdt --mgs /dev/sda3

Permanent disk data:
Target:     lustrefs-MDTffff
Index:      unassigned
Lustre FS:  lustrefs
Mount type: ldiskfs
Flags:      0x75
           (MDT MGS needs_index first_time update )
Persistent mount opts: errors=remount-ro,iopen_nopriv,user_xattr
Parameters: mdt.group_upcall=/usr/sbin/l_getgroups

checking for existing Lustre data: not found
mkfs.lustre: size ioctl failed: Inappropriate ioctl for device

mkfs.lustre FATAL: mkfs failed 19
_______________________________________________________________________

I'm running kernel 2.6.18.

Would you please help me in solving this problem?

Regards,
Ali

Something is wrong with your /dev/sda3. Lustre is not finding a proper
block device there, so it assumes you are using a loopback device, but
since you are not using a loopback, it fails (size is only used with
loopback) Verfiy that sda exists, and is partitioned correctly. (sda3
exists)
As a test, make an ext2 FS on sda3 with mkfs. If that works, Lustre
should work fine.

This is bug 14647.
Lustre wrong assume about use loop device if real block device not
exist. check you /dev directory for sda3 entry.
