Hi,
surely my action was to test environment, in a production environment,
I would have placed
all the files before deleting the server OST1.
However, I tried to do:
unlink zero.dat
unlink: cannot unlink `zero.dat': Invalid argument
and then:
ls -lrt
total 12475308
?--------- ? ? ? ? ? zero.dat
?--------- ? ? ? ? ? ubuntu-9.10-dvd-i386.iso
?--------- ? ? ? ? ? XXXXXXXXX_CentOS-5.4-
x86_64-bin-DVD.iso
?--------- ? ? ? ? ? Windows_XP-Capodarco.iso
?--------- ? ? ? ? ? UBUNTU_CentOS-5.4-
x86_64-bin-DVD.iso
?--------- ? ? ? ? ? KK_CentOS-5.4-x86_64-
bin-DVD.iso
?--------- ? ? ? ? ? FFFFF_CentOS-5.4-x86_64-
bin-DVD.iso
?--------- ? ? ? ? ? CentOS-5.3-i386-bin-
DVD.iso
?--------- ? ? ? ? ? BBBBB_CentOS-5.4-x86_64-
bin-DVD.iso
?--------- ? ? ? ? ? BAK_CentOS-5.4-x86_64-
bin-DVD.iso
?--------- ? ? ? ? ? 2.iso
and the log messages:
Jun 3 14:05:29 mdt02prdpom kernel: LustreError: 16265:0:(lov_ea.c:
248:lsm_unpackmd_v1()) OST index 1 missing

84:lov_dump_lmm_objects()) stripe 0 idx 1 subobj 0x0/0x62
For the Kernel Panic console messages, I have them only as an image, I
can attach to email ?
For the second problem:
doing tests with Quotas, when I go to run the command:
lfs quotacheck -ug /LUSTRE/
quotacheck failed: Input/output error
and the log say:
kernel: LustreError: 7103:0:(quota_check.c:251:lov_quota_check()) lov
idx 1 inactive
Is there any suggestion ?
Thanks
Cheers, Stefano

A clarification on what I wrote, the command that go server MGS/MDS
in Kernel Panic is:
My version of Lustre is 1.8.3
By testing, I tried to delete a OST and replace it with another OST
and now the situation is this:
cat /proc/fs/lustre/lov/lustre01-mdtlov/target_obd
0: lustre01-OST0000_UUID ACTIVE
2: lustre01-OST0002_UUID ACTIVE
- first problem
lustre01-OST0001_UUID ACTIVE is the OST was canceled and it had
files,
which of course now there are not more:
Ideally, you should migrate files off the OST before deleting it.
ls -lrt

I to delete them, follow these steps:
You should be able to delete them from the client with "unlink
zero.dat", which will return an ENOENT error, but the file should be
gone. No need to run lfsck at all.
and the server MGS/MDS go to in Kernel Panic
What do the MDS console messages say? That is the root of the
problem.
Cheers, Andreas
