Mysql 5.6, Centos 7 and errno: 24 - Too many open files
Hi,
may be somewon has a working solution and information on that:
I installed the most recent mysql community on a server and do get a lot
of "errno: 24 - Too many open files".
There are suggestions to increase the open_files_limit, change/add that
to /etc/security/limits.conf and modify the systemd script by hand.
Depending on how you start mysql (restart, or at systemboot time

Hi Johan,
Does systemd also overrule /etc/my.conf?
Thx!

Oldies but Goldies - Dovecot 1.2 and Sieve
Hi,
we still run dovecot 1.2.17 and upgrading is not planed for some time.
But I'm asked to install a sieve system to be used with SOGo soon.
What do I have to install / configure?
Is installing/configuring the dovecot-sieve-0.1.19 and
dovecot-managesieve-0.11.13 enough?
We still use mostly the default settings for imaps/pop3s.
And of course configure SOGo.
Thanks for any feedback.

strange diskspace consuming
Hi,
I do a tgz-backup some maildir-folders with n*1000 off files and a lot
of GB in storage. The backuped maildirs are removed after the tar.
My assumption was, that the free diskspace should be bigger after that,
but from what I get with df, it looks like I'm loosing space.
Currently the tgz is saved on the same disk/mountpoint.
Any hint, why removing the maildirs dont free diskspace as

rsync stuck at +- 50 MB/s, cp and scp are +- 200 MB/s
Hi,
i have two servers, connected to to the lan by 10Gb with 10Gb and DAS
hardware raid.
Each system con read and write locally or to the 10G iscsi by more than
200 MB/s.
Now I have to transfer backups form A to B and doing this with rsync
always stuck at +- 48-50MB/s no matter which options, compressions,
encryption etc I use. Even the plain default rsync is at that 50 Mb limit.

File isn't in mbox format - error
HI,
I recently upgraded an wu-imap server to dovecot dovecot-0.99.11-1.FC3.3
without big trouble (the subscribed mailboxes had to be added by hand...)
But today users told me that there where some problems; e.g. a user
tried to delete a message and got this error:
Oct 19 09:43:13 mail imap(jmeinken): File isn't in mbox format:
/home/mitarbeiter/jmeinken//Trash

AW: strange copy speed
Hello G?tz,
could you do a closer look at your smbd (maybe with truss or strace)
to see what exactly happens? or maybe it would be enough to watch
traffic between your client and server (and traffic between your
server and nameserver, domaincotroler (if involved))
best regards,
chris

Setting up large (12.5 TB) filesystem howto?
Hi,
I'm trying to set up an iscsi 12.5 TB storage for some data backup.
Doing so, I had some difficulties to find the right tool, maybe it's
also a question of the system settings...
The server is a 32Bit CentOS 5.3 with the recent updates. Ths iscsi
connection can be establised.
fdisk and parted fail to create any information on the device or fail
completely.

Filesystem labeling confusion or mess up
Hi,
I do have an iscsi storage with two raidsets. I'm logged in to the
target and get two devices: /dev/sdb and /dev/sdc.
After formatting the devices with ext4 I realised, that I had used a
wrong label, so I tried to relabel the devices.
But now I'm confused:
doing a e2label /dev/sdb or /dev/sdc returns always the same label name
for both devices.
so I did "e2label /dev/sdb

suggestions for a "fast" fileserver - 1G / 10G
Hi,
I'm looking for some recommendations for a "fast" fileserver regarding
the hardware you use.
We have different fileservers as our requirements changed over time.
The "main" problem we are faced with is, that with smb (windows 7 and OS
X) clients we never get really close to GBit speed on reads or writes.
Using the same servers/storages with ftp, ssh, rsync, nfs we

Same home path on multiple servers - how to ?
Hi,
I have a samba 3.6 PDC with ldap backend.
Now I'd like to add an other storage samba server which uses the same
home directory structure as the PDC.
I have configured the new server using winbind, so the users can log in
with the password stored in ldap.
But the home directory stored in ldap is not used; the new server
searches in /home/UID or /home/DOMAIN/uid.

question regarding rw-access on mailbox on creation/login (dovecot 1.2.17)

/var/mail is rw by root.mail

strange disk space calculation ext4 df and du
Hi,
in one server I do have a SSD raid 1 size 219GB.
df shows 9.4 GB free, 198GB used.
If I do "du -sch * | sort -h -r" on /, I just have close to 3.5GB used ....
Any hints, what's eating up the space?
Centos 6.6, fs = ext4.

Suggestions for upgrading dovecot 1.0.7 Redhat EL 5.x
Hi,
we still have our solid rock dovecot 1.0.7 Redhat el 5.x up and running.
We don't need much magic or special setups.
However we'd like to think what might be the next step in upgrading our
setup. Each user one mbox mailbox. About 500 imap/pop3 accounts, 400GB data.
First of all: to what version is a good step from 1.0?
Can we get a rpm from e.g. atrpms repository?
Dose anyone has
