suggestion for filesystem or general performance optimization
Hi, recently I noticed, that we have some performance issues regarding our central samba fileserver. Red Hat EL 5.8, samba3x-3.5.10-0.109. Doing a rsync, scp or accessing a share from a client and copy large files (e.g. 3 GB ISO), I do get a read / write average about 60 to 90 MB/sec. So LAN and general hardware can work at max. lan speed. But copying or syncing small files, e.g. user profiles

Suggestions? Multiple servers/storages one domain
Hi, currently we do have one samba3x-3.5.10-0.109.el5_8 RH EL 5.8 PDC authenticating by our central LDAP server. This PDS also hosts the central fileserver storage for all our +- 600 users, some group shares and roaming profiles. The clients are OS X, Win XP and Win 7. We hope to have all XP 'killed' by end of the year. Furthermore we do have a second stand alone samba server for some

Strange Performance Issue / concurrent clients -> very very slow
Hi, recently I installed a new GBit connected iSCSI Storage to one of our fileservers. Redhat EL Linux 5.7 samba3x-3.5.4-0.83.el5, kernel 2.6.18-238.19.1.el5PAE, Dell Poweredge 1750, dual Xeon. The transfer speed is very very different, depending on the method I use. Currently I'm the only user accessing that server and there is low network traffic. I know, that there are some overheads

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

Pittfals Windows 7 and samba 3.3.8 (centos 5.5), LDAP BE - joining domain
Hi, recently I got my samba/ldap/pdc setup up and running with xp clients. Server: centos 5.5, openldap-2.3.43-12 and samba3x-3.3.8. The new challenge: adding Windows 7 Clients and upgrading to samba 3.3.x I followed a posting from the centos forum (1) which worked so far for the samba update breaking nothing for xp. Than I installed a windows 7 client with the latest patches, changed the

You suggestion for 'big' filesystem management Best Practice?
Hi, we plan to set up a big file storage for media files like uncompressed movies from student film projects, dvd images etc. It should be some sort of archive and will not bee accessed by more than may be 5 people at the same time. The iSCSI RAID we have is about 26TB netto and I'm again faced with the question: How many partitions, which filesystem, which mount options etc. For the User

Upgrading from 1.2.x -> 2.2.x in one step possible
Hi, after some off-ML discussions to and some reconsiderations, we might do the "big jump" from our current 1.2.17 to the atrpms 2.2. From googling and reading the dovecot upgrade wiki I don't see any (big) pitfalls. Basically we use the default config options, mbox, pop3s/imaps on RH EL 5. So "just" run the upgrade-config script, fingers crossed and thats it? Ii it

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.

Mysql 5.6, Centos 7 and errno: 24 - Too many open files
Gotz, This is due to systemd, it overrules your settings. Add a file to systemd config fixes it: [root at mysql2 ~]# cat /etc/systemd/system/mariadb.service.d/limits.conf [Service] LimitNOFILE=10000 LimitMEMLOCK=10000 On Wed, Apr 29, 2015 at 8:31 AM, G?tz Reinicke - IT Koordinator < goetz.reinicke at filmakademie.de> wrote: > Hi, > > may be somewon has a working solution and

Carl, By default my.cnf has to obey the OS limits, so in this case the order is: systemd > /etc/security/limits* > /etc/my*. On Wed, Apr 29, 2015 at 3:22 PM, Carl E.

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
