inclined to think the disk has I/O issues, though you mentioned repair claims there's nothing needed.

Any suspicious logs in /var/log

or try dd if=/dev/yourdisk of=/devnull

to see if that triggers I/O errors in the logs

Greetings,

Hope everyone's summer is going well.

Weird problem here on an RHEL 7 box. Have a number of files under /home that the os will not let me read. So tools like cp, md5sum, lsattr and such, and applications, all tell me "operation not permitted" whether run as user or as root. That said I can stat them. Have checked ownership, permissions, file acls, etc.

Haven't found a pattern to the affected files. One interesting example is a directory of ~300 conference papers, all pdfs, all from same conference, all with identical perms and ownership, and exactly one of them has this problem. The rest I can read as normal.

Running selinux but disabling that didn't change anything.

It's an XFS filesystem. Ran xfs_repair but no change.

I'm stumped! Any ideas?
Thanks as always...

Judah
