Hi, I managed to set up a simple lustre fs but one of the ost is inactive as shown at the client. I had 1 MDT and 1 Ost(active) on one pc, however the other OST on another pc is inactive. Hope i can get some advice/input. Here''s my output: *Client* [root at CLIENT /]# lfs df -h UUID bytes Used Available Use% Mounted on lustre-MDT0000_UUID 1.7G 83.2M 1.6G 4% /lustre[MDT:0] lustre-OST0000_UUID 3.9G 168.2M 3.6G 4% /lustre[OST:0] OST0001 : inactive device filesystem summary: 3.9G 168.2M 3.6G 4% /lustre *MDS/OST PC* [root at dhcp-192-168-36-219 ~]# lctl dl 0 UP mgs MGS MGS 9 1 UP mgc MGC192.168.36.219 at tcp 8322e410-9f83-a145-4bc1-bb3685e458ff 5 2 UP lov lustre-MDT0000-mdtlov lustre-MDT0000-mdtlov_UUID 4 3 UP mdt lustre-MDT0000 lustre-MDT0000_UUID 5 4 UP mds mdd_obd-lustre-MDT0000-0 mdd_obd_uuid-lustre-MDT0000-0 3 5 UP ost OSS OSS_uuid 3 6 UP obdfilter lustre-OST0000 lustre-OST0000_UUID 7 7 UP osc lustre-OST0000-osc-MDT0000 lustre-MDT0000-mdtlov_UUID 5 8 UP osc lustre-OST0001-osc-MDT0000 lustre-MDT0000-mdtlov_UUID 5 *OST Only PC* [root at OSS1 /]# lctl dl 0 UP mgc MGC192.168.36.219 at tcp 205406aa-c943-f917-5962-3433068b4383 5 1 UP ost OSS OSS_uuid 3 2 UP obdfilter lustre-OST0001 lustre-OST0001_UUID 5 -------------- next part -------------- An HTML attachment was scrubbed...
