[Lustre-discuss] Seeing OST errors on the OSS that doesnt have it mounted

[Alex Lee]

I'm getting these error messages on my OSS. However the OST006 is not mounted on this OSS(lustre-oss-0-0).  OST0006 is visible to the server because lustre-oss-0-0 is the failover node for lustre-oss-0-1 which does mount OST0006.

Should I be worried about these errors? I dont understand why the OSS is even giving these errors out since there is no hardware issue that I can see. Also the OST is not mounted on that OSS I would think its "invisible" to the OSS.

I only get these errors during lustre usage. When the filesystem is not used I never get any errors.

Clip of the log below.

Thanks,
