Hello,
I have some problems in my filesystem. When I browse the filesystem from a
client, a specific directory have directories that contain the same directories,
in other words:
LustreFS-> dir A -> dir B -> dir B -> dir B -> dir B -> dir B…
This directory, and its children, has the same obdidx/objid:
[root@client vm-106-disk-1.raw]# lfs getstripe vm-106-disk-1.raw
vm-106-disk-1.raw/vm-106-disk-1.raw
lmm_stripe_count: 1
lmm_stripe_size: 1048576
lmm_pattern: 1
lmm_layout_gen: 0
lmm_stripe_offset: 19
obdidx objid objid group
19 7329413 0x6fd685 0
[root@client vm-106-disk-1.raw]# cd vm-106-disk-1.raw/
[root@client vm-106-disk-1.raw]# pwd
/mnt/data/106/GNUSparseFile.2227/vm-106-disk-1.raw/vm-106-disk-1.raw/vm-106-disk-1.raw
[root@client vm-106-disk-1.raw]# lfs getstripe vm-106-disk-1.raw
vm-106-disk-1.raw/vm-106-disk-1.raw
lmm_stripe_count: 1
lmm_stripe_size: 1048576
lmm_pattern: 1
lmm_layout_gen: 0
lmm_stripe_offset: 19
obdidx objid objid group
19 7329413 0x6fd685 0
[root@client vm-106-disk-1.raw]# cd vm-106-disk-1.raw/
[root@client vm-106-disk-1.raw]# pwd
/mnt/data/106/GNUSparseFile.2227/vm-106-disk-1.raw/vm-106-disk-1.raw/vm-106-disk-1.raw/vm-106-disk-1.raw
[root@client vm-106-disk-1.raw]# lfs getstripe vm-106-disk-1.raw
vm-106-disk-1.raw/vm-106-disk-1.raw
lmm_stripe_count: 1
lmm_stripe_size: 1048576
lmm_pattern: 1
lmm_layout_gen: 0
lmm_stripe_offset: 19
obdidx objid objid group
19 7329413 0x6fd685 0
But when I mount the MDT with “Ldiskfs” I can see correctly the filesystem in
the “ROOT” mdt directory.
I wish to remove from the client this looped directory (dir B in the example),
but when I try to remove I get a “kernel panic" in the MDS/MGS.
is it a good idea remove a subdirectory in the MDT (with Ldiskfs mounted) in the
“ROOT” mdt directory or I will get orphan objects in the OST, if I remove this
directory in the MDT?
Thanks!!!
