Our vendor gave us a workaround for this bug to increase the time in which the client will shrink the granted space. The default value is 20 minutes, to prevent the grant space from going out of sync again you can increase this value to a higher one via the following command (on mgs server for every OST): lctl conf_param $FSNAME-OST0000.osc.grant_shrink_interval=63072000 (replace FSNAME with the name of your filesystem) First you have to reboot at least all clients and (better) all servers. This workaround works well for us. best regards, Christian > > > On Apr 23, 2012, at 9:18 AM, Gretchen Zwart wrote: > >> Hi, >> Debian 5.0 >> 2.6.26-2-amd64 SMP (SLES 11) >> Lustre 1.8.1.1-1 >> >> Lustre clients are getting ENOSPC -28 error messages but 'lfs df' >> results indicate that OSTs are no more than 50% full.
