Hi, some time ago I removed some physical disks from a server and now I'm still getting dmesg messages like: sd 0:2:2:0: SCSI error: return code = 0x00040001 end_request: I/O error, dev sdc, sector 0 And all lvm tools still grumbel about that disks too: /dev/sdb: read failed after 0 of 4096 at 0: Eingabe-/Ausgabefehler /dev/sdb: read failed after 0 of 4096 at 1746969493504:

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, I have an iscsistorage which I attached to a new centos 6.3 server. I added logic volumes as usual, the block devices (sdb & sdc) showed up in dmesg; I can mount and access the stored files. Now we did an firmware software update to that storage (while unmounted/detached from the fileserver) and after reboot of the storage and reatache the iscsi nodes I do get new devices. (sdd &

Hi, it is possible to create and setup/format volumes on a iscsi storage on one server and than disconnect and attache the storage to an other server. AFAIK on the 'new' server I do have to launch an LVM-scan command ... after login to the iscsi target. But which LVM-command and syntax was it? Thanks for any hint! :) /G?tz -- G?tz Reinicke IT-Koordinator Tel. +49 7141 969 420 Fax

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, 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, 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

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, 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.
