I upgrade using YUM my CentOS 4 system the other night. I was noticing that X wasn't coming up because of a gdk_thread issue (actually, the window manager wasn't starting. I cold get X to start from the command line). Surprised that it took 587MB of downloads, since I was current as of September 29th. When rebooting, I was forced to the login prompt, because my LVM group with

Hello, I have some performance problems in a file server system. It is used as Samba and NFS file server. I have some ideas what might cause the problems, and I want to try step by step. First I have to learn more about these areas. First I have some questions about tuning/sizing the ext3 journal. The most extensive list I found on ext3 performance tuning is

Hi there, I'm using xen-3.0.2.2-86.1_rhel4.1 on a Redhat AS 4 update 1 for i386.

Hi, I have a strange problem with user quotas enabled on a xfs filesystem and samba 3.0.21c: When a standard block device (e.g. /dev/sdc1) is used for the fs, quota works like expected: /dev/sdc1 on /mnt/tmp type xfs (rw,usrquota) output from level quota:10 debug: [2006/04/19 14:38:48, 10] lib/sysquotas.c:sys_get_quota(394) sys_get_quota() uid(4004, 4004) [2006/04/19 14:38:48, 10]

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, one more LVM thing: on one server some LVM stores are physically removed but still there are some informatione somwher spread adcross teh server. e.g. if I do a vgdisplay or pvcreat I get an error regarding that old storage: /dev/raid_10/lvol0: read failed after 0 of 4096 at 14000515383296: Eingabe-/Ausgabefehler How can I remove all information?

Hi, One of the problems we are facing is secure storage of passwords (database, bestcrypt, other applications/systems, ) and availability within users' scripts (perl, python, ...) or applications (Java, C, ). I'm sure that there are quite a few people who are facing the same issue and there are quite a few home made solutions, such as password obfuscators and/or solutions based on the

Hi everyone, I've noticed a problem with Debian wheezy + samba 3.6.6 configured with acl_xattr in my configuration.
