Chris, IIRC, that shows up because at some point during the uptime of your MDT/MGS that OST was in the mix. It registered and will stay there until you have completely restarted the filesystem.
I have had that in the past and my solution was to bring the system up EXCEPT for the OST that I didn't want/need listed, which, at the time, was on broken hardware.

I am adding OSTs to a lustre 2.5 filesystem. I'm working with 2 OSS servers: srv1 & srv2. srv1 hosts ost indices 0,2,4,6, srv2 hosts ost indices 1,3. We just added ost indices 4 & 6 and will add 5 & 7 later. I ran lfs command on a client. I found "lfs osts" gave correct output (ie. ost index 5 not listed) > # lfs osts > OBDS:: > 0: testfs-OST0000_UUID ACTIVE > 1: testfs-OST0001_UUID ACTIVE > 2: testfs-OST0002_UUID ACTIVE > 3: testfs-OST0003_UUID ACTIVE > 4: testfs-OST0004_UUID ACTIVE > 6: testfs-OST0006_UUID ACTIVE However "lfs df" command gave an error about ost index 5 missing eg) > # lfs df -h > UUID bytes Used Available Use% Mounted on > testfs-MDT0000_UUID 371.5G 77.8M 346.7G 0% > /lustre/testfs/client[MDT:0] > testfs-OST0000_UUID 14.2T 23.6M 13.5T 0% > /lustre/testfs/client[OST:0] > testfs-OST0001_UUID 14.2T 24.7M 13.5T 0% > /lustre/testfs/client[OST:1] > testfs-OST0002_UUID 14.2T 23.6M 13.5T 0% > /lustre/testfs/client[OST:2] > testfs-OST0003_UUID 14.2T 23.6M 13.5T 0% > /lustre/testfs/client[OST:3] > testfs-OST0004_UUID 14.2T 11.6M 14.1T 0% > /lustre/testfs/client[OST:4] > OST0005 : Resource temporarily unavailable > testfs-OST0006_UUID 14.2T 11.6M 14.1T 0% > /lustre/testfs/client[OST:6] This appears to be a minor reporting issue. chris hunter [email protected] _______________________________________________ lustre-discuss mailing list [email protected] http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org _______________________________________________ lustre-discuss mailing list [email protected] http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
