But I get mount errors saying below. Since the FS in question mount fine so long as I don’t specify finobts=1 while formatting, should I assume the rest of 7.1 is not yet ready for it? Or is there some option I missed?</div><div class=""><br class=""></div><div class="">thanks,</div><div class="">Chuck</div><div class=""><div style="margin: 0px; font-family: Courier; color: rgb(76, 47, 45); background-color: rgb(223, 219, 196);" class=""><span style="font-variant-ligatures: no-common-ligatures; color: #ee2207" class=""><b class="">xfs</b></span>progs-3.2.1-6.el7.x86_64</div></div><div style="margin: 0px; font-family: Courier; color: rgb(76, 47, 45); background-color: rgb(223, 219, 196);" class=""><div style="margin: 0px;" class="">kernel-3.10.0-229.1.2.el7.x86_64</div></div><div class=""><div style="margin: 0px; font-family: Courier; color: rgb(76, 47, 45); background-color: rgb(223, 219, 196);" class="">[75881.037768] SELinux: initialized (dev dm-7, type xfs), uses xattr</div><div style="margin: 0px; font-family: Courier; color: rgb(76, 47, 45); background-color: rgb(223, 219, 196);" class="">[75908.498994] XFS (dm-7): Superblock has unknown read-only compatible features (0x1) enabled.</div><div style="margin: 0px; font-family: Courier; color: rgb(76, 47, 45); background-color: rgb(223, 219, 196);" class="">[75908.499035] XFS (dm-7): Attempted to mount read-only compatible filesystem read-write.</div><div style="margin: 0px; font-family: Courier; color: rgb(76, 47, 45); background-color: rgb(223, 219, 196);" class="">Filesystem can only be safely mounted read only.</div><div style="margin: 0px; font-family: Courier; color: rgb(76, 47, 45); background-color: rgb(223, 219, 196);" class="">[75908.499058] XFS (dm-7): SB validate failed with error 22.</div></div><div style="margin: 0px; font-family: Courier; color: rgb(76, 47, 45); background-color: rgb(223, 219, 196);" class=""><br class=""></div><div style="margin: 0px; font-family: Courier; color: rgb(76, 47, 45); background-color: rgb(223, 219, 196);" class=""><br class=""></div><div style="margin: 0px; font-family: Courier; color: rgb(76, 47, 45); background-color: rgb(223, 219, 196);" class=""><div style="margin: 0px;" class="">[root@NIAIRPGL1 share]# modinfo xfs</div><div style="margin: 0px;" class="">filename: /lib/modules/3.10.0-229.1.2.el7.x86_64/kernel/fs/xfs/xfs.ko</div><div style="margin: 0px;" class="">license: GPL</div><div style="margin: 0px;" class="">description: SGI XFS with ACLs, security attributes, large block/inode numbers, no debug enabled</div><div style="margin: 0px;" class="">author: Silicon Graphics, Inc.</div><div style="margin: 0px;" class="">alias: fs-xfs</div><div style="margin: 0px;" class="">rhelversion: 7.1</div><div style="margin: 0px;" class="">srcversion: 3E3940432E169BEE955EDE9</div><div style="margin: 0px;" class="">depends: libcrc32c</div><div style="margin: 0px;" class="">intree: Y</div><div style="margin: 0px;" class="">vermagic: 3.10.0-229.1.2.el7.x86_64 SMP mod_unload modversions </div><div style="margin: 0px;" class="">signer: CentOS Linux kernel signing key</div><div style="margin: 0px;" class="">sig_key: 34:B5:BC:A2:B7:06:D8:2E:72:A5:BE:3E:E4:09:BE:C7:19:5E:A5:08</div><div style="margin: 0px;" class="">sig_hashalgo: sha256</div><div class=""><br class=""></div></div></body></html>
