[HPDD-discuss] Problems on Lustre 2.7.0

We are running Lustre 2.7.0. # uname -r 2.6.32-504.8.1.el6_lustre.x86_64 The combined mgsmdt load jumped up yesterday, and stayed high since, with a couple of really outrageous peaks. Ended up power cycling, as the mdt would not umount. It seems to be performing fine now, but while watching logs, I am seeing a fair number of these now in /var/log/messages 2015-06-10T20:25:51-04:00 mdtmgs.aglt2.org kernel: [ 936.535168] LustreError: 3932:0:(tgt_lastrcvd.c:800:tgt_last_rcvd_update()) umt3B-MDT0000: trying to overwrite bigger transno:on-disk: 17180113246, new: 17180113245 replay: 0. see LU-617. 2015-06-10T20:27:24-04:00 mdtmgs.aglt2.org kernel: [ 1029.720722] LustreError: 4038:0:(tgt_lastrcvd.c:800:tgt_last_rcvd_update()) umt3B-MDT0000: trying to overwrite bigger transno:on-disk: 17180141036, new: 17180141035 replay: 0. see LU-617. 2015-06-10T20:33:54-04:00 mdtmgs.aglt2.org kernel: [ 1419.740272] LustreError: 3892:0:(tgt_lastrcvd.c:800:tgt_last_rcvd_update()) umt3B-MDT0000: trying to overwrite bigger transno:on-disk: 17180255177, new: 17180255176 replay: 0. see LU-617. 2015-06-10T20:35:38-04:00 mdtmgs.aglt2.org kernel: [ 1524.040242] LustreError: 3926:0:(tgt_lastrcvd.c:800:tgt_last_rcvd_update()) umt3B-MDT0000: trying to overwrite bigger transno:on-disk: 17180285251, new: 17180285250 replay: 0. see LU-617. So, I found a couple of LU that seem relevant, but this older one best replays the same kind of errors. https://jira.hpdd.intel.com/browse/LU-5283 This one also popped up in a search. https://jira.hpdd.intel.com/browse/LU-5939 It bothers me in particular because it says Critical Bug in 2.7.0, solved for 2.8.0 What, if anything, should I be doing about this? Should I worry that I will lose my mdt? I might not ever be able to return to my office if that happens. Thanks, bob
