[Lustre-discuss] finding files belonging to dead/offline ost

[Hendelman, Rob]

Hello,

We recently had an OST become badly corrupted (850G or so in
lost+found).  I deactivated this OST on the MDT server & the clients.
The OST is not mounted on the OSS (not possible).

I would like to determine which files were on that OST.

On one of the clients, I tried the following:

"lfs find -O fs01-OST00005-osc-fff810800335400 /mnt/lustre/fs01" does
not return anything.
"lfs getstripe -O fs01-OST0005-osc-ffff810800335400" returns "error:
setup_obd_uuid: unknown obduuid: fs01-OST0005-osc-ffff810800335400"

Lctl dl returns ost5 as: 

8 UP osc fs01-OST0005-osc-ffff810800335400
6df4e008-e988-d8d0-d50e-cad4d448183c 5

Any suggestions?

Did I miss something obvious?  This data has to be somewhere in the mdt,
correct?
