Some non-recommend way, but if you really have no other way, you can try. 1) umount the MDT device 2) mount the MDT device as 'ldiskfs' 3) find the target 'progs' under /ROOT/ 4) backup the progs' lma EA 5) remove the progs' lma EA 6) rename 'progs' as 'tmpname' under the parent directory 7) remount the MDT device as 'lustre' 8) mount a new client, 'stat /absolute_path/tmpname'
If the 'stat' works, then you can rename 'tmpname' back as 'progs' under the 'lustre' mode. NOTE: Please backup the 'progs' lma EA before make any changes, then if something was wrong, you can restore the 'progs'. -- Lucky, Nasf > -----Original Message----- > From: Tommi T [mailto:tommi_...@yahoo.com] > Sent: Thursday, June 12, 2014 10:30 PM > To: Yong, Fan; lustre-discuss > Subject: Re: [Lustre-discuss] Directory access triggers OI scrub > > Yes, also with different client versions. > > el6: lustre-client-2.1.6/2.5.1 > > cray: lustre-client-2.4.1-3.0.101_0.29_default > > > > > On Thursday, June 12, 2014 5:18 PM, "Yong, Fan" <fan.y...@intel.com> > wrote: > Have you tried it with new mounted client after the upgrading? > > -- > Regards, > Nasf > > > > > > -----Original Message----- > > From: Tommi T [mailto:tommi_...@yahoo.com] > > Sent: Thursday, June 12, 2014 8:58 PM > > To: Yong, Fan; lustre-discuss > > Subject: Re: [Lustre-discuss] Directory access triggers OI scrub > > > > Hi, > > > > Still same error.
