[Lustre-discuss] lfs --obd discrepancy to lctl dl (1.8.3)

[Heiko Schröter]

Hello,

lfs prints different obd(idx) compared to lctl dl. We use single striping.


cluster1 tmp # lfs find --obd scia-OST0017_UUID /data/scia/L0/V0.00/20100327/SCI_NL__0PNPDE20100327_193441_000040582088_00071_42209_1158.N1

According to "lfs find" the stripe should be on scia-OST0017_UUID. "lfs gestripe" reports to have it on obdidx 23 , which is scia-OST0014 according to lctl dl.
Which one is true ? As fas as i remember it worked correctly in 1.6.6.


We updated currently from 1.6.6 to 1.8.3. Could have been something broken during upgrade ?

Thanks and Regards
