Some files get written with 000 permissions randomly, can't delete them

Hi community,

I've been updating OpenSSL and SecureShell in a cluster of HP-UX 11i v3 machines but in some of them I've noticed that when making a backup, randomly some files would get written with 000 permissions and there's no way to delete them, even as root.

This is one example:

[dbm:/opt/ssh.old/etc]$ ll sshd_config
----------   1 root       sys           4726 Jun 10 14:16 sshd_config
[dbm:/opt/ssh.old/etc]$ chmod 644 sshd_config
chmod: can't change sshd_config: Permission denied
[dbm:/opt/ssh.old/etc]$ rm -f sshd_config
rm: sshd_config not removed.  Permission denied
[dbm:/opt/ssh.old/etc]$ id
uid=0(root) gid=3(sys) groups=0(root),1(other),2(bin),4(adm),5(daemon),6(mail),7(lp),20(users)
[dbm:/opt/ssh.old/etc]$

And in another machine, when updating OpenSSL it had trouble in one fileset in the same way:

ERROR:   utime of file "/opt/openssl/1.1/doc/man1/passwd.pod" failed.
         Permission denied (13).
ERROR:   chown "bin.bin" "/opt/openssl/1.1/doc/man1/passwd.pod" failed.
         Permission denied (13).
ERROR:   Failed installing fileset

Could it be a storage problem? It seems to happen randomly. Any help to pinpoint the issue is appreciated.

Hello douteiful,

Please check the permission of the directories involved , such as /opt .
Also you may check if there is any permission issue with directory /usr/ , /usr/sbin or with /sbin where the binaries are located .

You may try change the permission of the file using /sbin/chmod or remove the file using /sbin/rm and see if that helps .
Also check if you have any third party Kernel Security module active in server , if so deactivate it and see if that helps .
