Re: [HPDD-discuss] hung lustre file system

unfortunately, that didn't work… I shutdown all clients, unmounted the mds and ost's and tuner.lustre --writeconf on all the lustre servers. I then remounted the mds, then the ost's and everything appears to be just fine (ie. all the mounting worked etc). BUT on a client OST000e : inactive device OST000f : inactive device and on the oss 2 UP obdfilter l1-OST000e l1-OST000e_UUID 5 3 UP obdfilter l1-OST000f l1-OST000f_UUID 5 and on the mds 19 UP osc l1-OST000e-osc-MDT0000 l1-MDT0000-mdtlov_UUID 5 20 UP osc l1-OST000f-osc-MDT0000 l1-MDT0000-mdtlov_UUID 5 On Wed, Mar 13, 2013 at 12:19 AM, Colin Faber <cfaber(a)gmail.com <mailto:cfaber@gmail.com>> wrote: Yeah basically it registered and now the MGS expects it. You're going to have to writeconf everything to get rid of that entry. -cf On 03/12/2013 10:15 AM, Stu Midgley wrote: Evening A mistake was made during the addition of 1 oss (2 ost's) to our online lustre file system.

We now have a hung file system. on the mds I see Mar 12 13:38:09 mds kernel: LustreError: 140-5: Server l1-OST000e requested index 14, but that index is already in use. Use --writeconf to force now what should I do? Bring everything down, writeconf all the servers and bring everything back up? reformat the ost? lfs df -h on a client is showing OST000e : inactive device Thanks. -- Dr Stuart Midgley sdm900(a)sdm900.com <mailto:sdm900@sdm900.com> <mailto:sdm900@sdm900.com <mailto:sdm900@sdm900.com>> _______________________________________________ HPDD-discuss mailing list HPDD-discuss(a)lists.01.org <mailto:HPDD-discuss@lists.01.org> https://lists.01.org/mailman/listinfo/hpdd-discuss -- Dr Stuart Midgley sdm900(a)sdm900.com <mailto:sdm900@sdm900.com> _______________________________________________ HPDD-discuss mailing list HPDD-discuss(a)lists.01.org https://lists.01.org/mailman/listinfo/hpdd-discuss
