Hi,
I have a defective OSS with a single OST that I was tying to remove from the
lustre filesystem completely (2.15.1). I was following
https://doc.lustre.org/lustre_manual.xhtml#lustremaint.remove_ost
I had drained the OST and was now using the commands with llog_cancel to remove
the config. This is where it went wrong. I first deleted attach, setup, add_osc
indexes for the 'client' and then needed to also delete those for MDT0000 and
MDT0001, but I accidentally removed two more indexes from the 'client'.
Now I have incomplete client llogs for one OST, I am missing the add_uuid and
attach lines for OST0002.
[root@mds ~]# lctl --device MGS llog_print lustre-client
- { index: 34, event: add_uuid, nid: 192.168.2.3@tcp(0x20000c0a80203), node:
192.168.2.3@tcp }
- { index: 35, event: attach, device: lustre-OST0001-osc, type: osc, UUID:
lustre-clilov_UUID }
- { index: 36, event: setup, device: lustre-OST0001-osc, UUID:
lustre-OST0001_UUID, node: 192.168.2.3@tcp }
- { index: 37, event: add_osc, device: lustre-clilov, ost: lustre-OST0001_UUID,
index: 1, gen: 1 }
- { index: 42, event: setup, device: lustre-OST0002-osc, UUID:
lustre-OST0002_UUID, node: 192.168.2.4@tcp }
- { index: 43, event: add_osc, device: lustre-clilov, ost: lustre-OST0002_UUID,
index: 2, gen: 1 }
Is there a way to recover from this ?
I hope someone can help.
Regards,
Martin Balvers
