Hello, I am using kernel 3.10 and would like to update xfsprogs (currently I have 3.1.5). When I tried to use the newest version of xfsprogs 4.3.0 I get the call trace about detected version 5 of superblock when mounting volume which was formatted using mkfs.xfs from 4.3.0.

Dave in thread http://oss.sgi.com/archives/xfs/2015-08/msg00528.html advises to disable crc and finobt: mkfs.xfs -m crc=0,finobt=0 but it does not work with 4.X version of xfsprogs. Call trace also occurred so I tried to use 3.2.4 family with crc=0,finobt=0 and volume mounted successfully. Dave also noticed: i.e. if Gentoo are shipping xfsprogs 3.2.4 w/ kernel 3.14.51, then Gentoo has a quality control problem - they have failed to verify that the packages they are shipping work correctly before shipping them to users... that using 3.2.4 with kernel 3.14.51 is not good idea so are you able to advise which version of xfsprogs is the best for kernel 3.10? Please note that update the kernel in my environment is not possible in easy way so I need to stay with 3.10. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
