List, I'm using lustre 2.0.
While i try to mount the client, i'm getting an error "File: Exists". It was working all the time before. After starting the heartbeat service for failover in OSS, some of the OST's are unmounted and mounted again. After that the client mount didn't work at all I've also attached the log below for your reference.. Please help me to sort it out... Logs Errors as below... 00010000:00080000:1.0:1290171315.880469:0:6554:0:(ldlm_request.c:1201:ldlm_cli_update_pool()) @@@ Zero SLV or Limit found (SLV: 0, Limit: 418116)
