Anyone know if it is possible to have multiple protocols instances with
different ssl_protocols settings?

ZFS on Linux repository
Hi list,
we all know why ZFS is not included in RHEL/CentOS distributions: its
CDDL license is/seems not compatible with GPL license.
I'm not a layer, and I do not have any strong opinion on the matter.
However, as a sysadmin, I found ZFS to be extremely useful, especially
considering BTRFS sad state. I would *really* love to have ZFS on Linux
more intergrated with current CentOS.

Dovecot, pigeonhole and hardlinks
Hi list,
many moons ago I asked about preserving hardlink between identical
messages when pigeonhole (for sieve filtering) was used.
The reply was that, while hardlink worked well for non-filtered
messages, using pigeonhole broke the hardlink (ie: some message-specific
data was appended to the actual mail file). Here you can find the

Per-protocol ssl_protocols settings
Hi all,
I have a question regarding the "ssl_protocols" parameter.
I understand that editing the 10-ssl.conf file I can set the
ssl_protocols variable as required.
At the same time, I can edit a single protocol file (eg: 20-pop3.conf)
to set the ssl_protocols for a specific protocol/listener.
I wander if (and how) I can create a different listener for another POP3

Deleted symlinks when receiveing files with the same name
Hi list,
I would like to know if the following rsync's behavior can be
changed/modified.
I noticed that when rsync receive a file for which the local filesystem
already has a symlinks with the same path/name, it _first_ delete the
symlink, _then_ it start the transfer.
I think there are two problems with this approach:
- it completely ignores the content of the symlinked files, which can

GlusterFS as virtual machine storage
Ciao Gionatan,
I run Gluster 3.10.x (Replica 3 arbiter or 2 + 1 arbiter) to provide
storage for oVirt 4.x and I have had no major issues so far.
I have done online upgrades a couple of times, power losses, maintenance,
etc with no issues. Overall, it is very resilient.
Important thing to keep in mind is your network, I run the Gluster nodes on
a redundant network using bonding mode 1 and I have

Windows guest skipping chkdsk if using Spice display
Hi all,
as per subject, when a Windows guest using a Spice display is rebooted
with a planned chkdsk, the consistency check is always skipped.
It seems that the Spice display issues some "phantom" keystrokes, which
are then intended by Windows as the "skip chkdsk at boot" signal.
I tried to use a Spice display with no additional features (ie: USB
redirection), but to no

GlusterFS as virtual machine storage
Solved as to 3.7.12. The only bug left is when adding new bricks to
create a new replica set, now sure where we are now on that bug but
that's not a common operation (well, at least for me).

Hi Aki, I probably misunderstood yor previous reply. So, the index will

- accessing the mailbox (ie: via IMAP).
This means that removing an email from the filesystem (ie: a u.* file)

Samba local user without /etc/passwd
Hi list,
I have a (naive?) question about samba local users.
My system: CentOS 6.6 w/Samba 3.6, connected to an AD Domain through
Winbind.
When creating a local user, I always first create a Unix user with
passwd and then I use smbpasswd -a <unixuser> to establish the mapping
between the tdbsam database and the local /etc/passwd file.
I wonder if, using the tdbsam in conjunction with
