[Users] unsupported deleted submount

[Konstantin Bukharov]

Hi,

You've missed kernel version.
Which one are you using?

Best regards,

Hi there,

We’ve done an maintenance for one server, and during the vz stop we saw this errors in syslog.

Dec 22 02:31:45 vs4 kernel: [24023142.154143] CPT ERR: ffff8800bf6cb000,110 :unsupported deleted submount:  (deleted)/var/named/chroot/etc/named.conf
Dec 22 02:32:48 vs4 kernel: [24023204.991986] CPT ERR: ffff880323705000,110 :unsupported deleted submount:  (deleted)/var/named/chroot/etc/named.conf
Dec 22 02:32:49 vs4 kernel: [24023205.458437] CPT ERR: ffff88043bcc0000,110 :unsupported deleted submount:  (deleted)/var/named/chroot/etc/named.conf

Till today we ignored the errors, but now had an client that says that named.conf has gone.

We are using CentOS 6 and openvz.repo, the client is using Centos 6 with named/bind with chroot(binmounts).

Is there a way to find and fix the problem so it cannot repeat?

I don’t want to see any cPanel server with virtfs with all files deleted just because we have rebooted the node.

Thank you
