Hi, I'm running a production server (Debian Sarge install) whose root filesystem (a software raid 1 array of 2 partitions of IDE drive) exhibited the following problem: Oct 28 06:00:06 server2 kernel: attempt to access beyond end of device Oct 28 06:00:06 server2 kernel: md2: rw=1, want=3050401328, limit=16353920 [...] a few of the above line snipped, want is different each time Oct 28

Hi, i was trying to install CentOS 5.1 on new machine based on Intel Q35 desktop board, witch 2 SATA disks (configured as RAID 1) , 8GB RAM and Intel Core2 QUADCORE. The first problem was with install - it hangs before installer startup at ACPI messages. So i installed it with ACPI=off switch. The first problem is : Dec 7 09:54:01 vmhost1 kernel: BIOS bug, no explicit IRQ entries, using default

I hope this is simple I have one kvm host that lists all my domains even after shut down. 'virsh list --all' shows machines in 'running' and 'shut off' states. If I copy those over to another machine and it only shows the virt machines in running state. vmhost2:~$ virsh list --all Id Name State ---------------------------------- 4 mybox4

Dear all, I generate data under IRT mdel. I conducted 1000 replications. When I run, some replication was not fit with my model. So, replications were fit model were less than 1000 replication.

Hi. I woke up this morning to find a ton of waiting emails complaining that some cron jobs on my system couldn't run because one of my filesystems (ext3 on software RAID 1) was suddenly mounted read-only. Always nice when you're away from the server due to travel. ;^> I investigated in the logs and found: 2007-08-02 04:02:25 kern.crit www kernel: EXT3-fs error (device md2):

CentOS 5, original kernel (xen and normal) and everything, Linux RAID 1. I rebooted one of my machines after doing some changes to RAID/LVM and now the two RAID partitions that I made changes to are "gone". I cannot boot into the system. On bootup it tells me that the devices md2 and md3 are busy or mounted and drops me to the repair shell. When I run fs check manually it just tells

Hi list, I'm new to Centos and I've a very small knowledge of selinux use. I can disable it, but I prefer take it on for study. I've a second mirrored device that I use for file sharing. This is the scenario: /dev/md2 mounted on /mnt/data To make samba working I must set the file context to the path at samba_share_t on /mnt/data. After this samba works. Now I'm setting up

Hi, My MUA (claws-mail) is having a hard time listing directories for a mail account with two namespaces, one of which using mbox and the other one using maildir to store mails.

Hi, I have two 320 GB SATA disks (/dev/sda, /dev/sdb) in a server running CentOS release 5. They both have three partitions setup as RAID1 using md (boot, swap, and an LVM data partition). # cat /proc/mdstat Personalities : [raid1] md0 : active raid1 sdb1[1] sda1[0] 104320 blocks [2/2] [UU] md1 : active raid1 sdb2[1] sda2[0] 4192896 blocks [2/2] [UU] md2 : active raid1 sdb3[1]

Hi all, I'm setting up Centos4.2 on 2x80GB SATA drives. The partition scheme is like this: /boot = 300MB / = 9.2GB /home = 70GB swap = 500MB The RAID is RAID 1. md0 = 300MB = /boot md1 = 9.2GB = LVM md2 = 70GB = LVM md3 = 500MB = LVM Now, the confusing part is: 1. When creating VolGroup00, should I include all PV (md1, md2, md3)? Then create the LV. 2. When setting up RAID 1, should I

Hi. CENTOS 7.6.1810, fresh install - use this as a base to create/upgrade new/old machines.
