I'm not using SELinux or anhy other security frameworks on that machine, only plain unix permissions. Just check again, no ACLs, no EAs, no file attributes are set on these filesystems. The filesystems make heavy use of hardlinks, but files usually have no more than ~12 hardlinks, so that counter should not exceed the inode size either. > Typically there is 50-70 bytes of attribute space available in 256 > byte inodes, larger attributes or lots of them will push them out of > the inode.... 50 bytes sounds more than enought for holding only unix permissions. Does it matter that the filesystem is somewhat larger? Not too large though, all xfs filesystems are < 1TB in size. Thanks, Christian. -- BOFH excuse #211: Lightning strikes. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
