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. coyp by scp

Hi, I tried different encryptions like arc four, but always with the same result. BTW: googling shows some similar questions and they are stuck on set same speed +-. But non of that solutions helped me. /G?tz > Am 11.08.2015 um 12:14 schrieb Eero Volotinen <eero.volotinen at iki.fi>: > > Usually problem in encryption. > > try cipher arcfour or apply hpn patches to

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

Hi, we have a storageserver (Centos 6.4) with a dualport Intel 10G X520-2 Adapter. A QSan P600Q-D316 Storage is configured with 8*SATA Drives raid 5 for test, connected trought a Cisco UCS 6100 Series Fabric Interconnect 10G Switch. I formated the storage with ext4 defaults, one volume and got r/w rates about 10MB/s some up to 40MB/s .... VERY POOR.... So we returned the storage to our dealer

Hi, may be there are some best practice suggestions for the "best mode" for channel bonding interface? Or in other words, when should/would I use which mode? E.g. I do have some fileservers connected to the users lan and to some ISCSI Storages. Or some Webservers only connected to the LAN. The switches are all new cisco models. I've read sone docs (1), (2) and (3) so the theory

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, 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. regards .

Hi, I followed the "Optimizing CentOS for gigabit firewall" posting and as some posters wrote pf is soo sooo ssooooo mutch faster, I was thinking to give it a try. But I'm not familier to BSD so I was looking for some tools and found "pfsense" http://www.pfsense.org/ "pfSense is a free, open source customized distribution of FreeBSD tailored for use as a

Hi, forgot that... CIFS and NFS. May be we split both to different servers. One CIFS, one NFS. Regards . Götz Am 13.07.16 um 08:26 schrieb Garland McAlexander: > What shares will you be using?

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.

Hi Johan, Does systemd also overrule /etc/my.conf? Thx! Carl On Wed, 29 Apr 2015 14:58:52 +0200 Johan Kooijman wrote: > Gotz, > > This is due to systemd, it overrules your settings.

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

Thank you for clarifying this, Johan. Very much appreciated!

Hi, I did the upgrade frpom 1.2.x to 2.2.10 and had some warnings/errors on a very few accounts/mailboxes. All of them where permission related and solved. Dovecot rocks again. But on one mailbox I do get an error: Error: user rechnnugseingang-animationsinstitut: Initialization failed: Initializing mail storage from mail_location setting failed Error: Invalid user settings.

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 This didn't happen
