These filesystems aren't super old, and were all created with the default RHEL7 options. I'm not sure how to check that 64 bit inodes are being used, though. xfs_info says: meta-data=/dev/mapper/nas-faculty--08 isize=256 agcount=4, agsize=3276800 blks = sectsz=512 attr=2, projid32bit=1 = crc=0 finobt=0 spinodes=0 data = bsize=4096 blocks=13107200, imaxpct=25 = sunit=0 swidth=0 blks naming =version 2 bsize=4096 ascii-ci=0 ftype=0 log =internal bsize=4096 blocks=6400, version=2 = sectsz=512 sunit=0 blks, lazy-count=1 realtime =none extsz=4096 blocks=0, rtextents=0 WW> Do you set a fsid when you export the filesystem? I have never done so on any server. And note that the servers are basically unchanged for quite some time, while the problem I'm having is new. I want to find some server-related cause for this but so far I haven't been able to do so. It seems my best option now seems to be to migrate all data off of this server and then wipe, reinstall and see if the problem reoccurs. - J<
