Hello, Today a virtual server under my administration ran out of disk space, so I had to get extra space to it.. while it was running, because it's an important web server without any kind of HA/Load Balancing (don't do that, kids). So what happened, is that after another administrator had extended the disk from VMWare, I tried to extend it from the OS side. Everything went well,

Hello, What is the simpliest way to run Redhat 7.3 server as CentOS 5 domU? I see that Xen emulates Intel PIIX ATA controller for HVM domUs but latest kernel of Redhat 7.3 (2.4.20-20.7smp) has no ata_piix kernel module yet. Is it possible to download it somewhere or there is another way? :) And I'd like to avoid reinstalling them with the new OS. Preferably they'd just die their

Hello, What do you use to manage virtual Xen machines? Nothing complex though preferably. :) I've already converted some servers for a Xen dom0 and starting to loose the picture - which VM runs where and how much resources left on each server. Regards, Mindaugas

Hello, After some fiddling with the server now I have broken RAID1 with the "current" mirror on the disk with few unreadable sectors. If I try to re-add other disk to the mirror resync goes till those bad sectors and then starts from the beginning. And so on. Is it possible to somehow force resync to continue even after errors? Manual resync with dd would require a bit too long

Hi list, I have a SAN attached to a CentOS 4.2 server. I have expanded the size of the virtual disk within the SAN (by adding a new HD to the disk pool) and need CentOS to see the new size (CentOS see it as /dev/sdb). I'm using LVM. Do you know a method for the Volume Group to see that one of its harddisk is now bigger, without rebooting (it's not a problem with a reboot but since

Hi list. I''m running Xen 4.0.1 on Debian. I''m trying to live resize a block device : - I have a arbitrary block device in my dom0 (/dev/mapper/vm-vol42). - I start a PV domain with that device as a disk (disk = [''phy:/dev/mapper/vm-vol42,xvda,w'']). - I resize vm-vol42 in the dom0 (adding size only) - the dom0 sees the device''s new size. -

I got the following error, but there''s no "cycle" I commented out File["/dev/sdb3"] and it works, but of course would choke if I ran it and the requirement were not met err: Could not apply complete catalog: Found cycles in the following relationships: File[/dev/sdb1] => Exec[echo -e "0,290\n,290\n," | sfdisk /dev/sdb] Here''s the node: node

Hello, We just had our servers fitted with more disks. Most of the disks are growing existing RAID 1+0 channels, some are in new channels. Controllers and disks support live installation. I'd like to avoid a reboot just to let the system find that the disks are larger. All I can find so far suggests that its possible to rescan the disks, and even find the new geometry (e.g.

Hello all, I posted the whole disk encryption instructions in the forum that has been briefly discussed on the list. I joined the list per Ned's post on the thread. http://www.centos.org/modules/newbb/viewtopic.php?viewmode=flat&topic_id=15923&forum=42 I have a couple of questions about the process of creating a wiki. 1. How does the peer-review process work? 2. Is there a place

Hi. I added a disk to a hardware raid 5 array and now i want to expand the LVM physical volume. There are now 4 sas 146GB disks in the server. The virtual disk /dev/sdb from the raid controller has been resized successfully with the server management software osma. [root at srv1 ~]# fdisk -l /dev/sdb Disk /dev/sdb: 438.4 GB, 438489317376 bytes 255 heads, 63 sectors/track, 53309 cylinders

Hi everyone, I added a page under the HowTos for Encryption, and then added a guide for encrypting /tmp /swap and /home using cryptsetup and LUKS keys on LVM, when you already have partitions setup. http://wiki.centos.org/HowTos/EncryptTmpSwapHome Regards, Max

Sorry for the cross-post, but I do not know whether this is a bug in Free FDISK, memdisk, or neither. This problem is with Free FDISK 1.2.1 and memdisk 2.04. I am using PXELINUX+memdisk to boot to a virtual hard drive containing MS-DOS 6.22. This works fine; DOS boots and the virtual drive appears as C:. Now I want to use Free FDISK to partition the *physical* drive. But when I run any of the

Hi, Is it possible to create one raid volume of 3.3 TB (9550SX-8lp X WD5000YS - 8nos) and create a file system with ext3? (CentOs4.3 64bit) The maximum I am getting is 1.24tb and fdisk returns no more space available. But when I say fdisk /dev/sda it list full size of 3.3 TB. But I can not create partitions more than 1.24TB. Any idea? Thanks Rajeev -------------- next part

Hello, Recently we bought HP bl35 blades with LSI Logic SAS controllers. mpt* drivers works fine but I would like to somehow view status from command line. To monitor e.g. if one of the HDDs failed. I found mptutil on LSI Logic site but it just shows me configuration in quite cryptic form. Thanks, Mindaugas

Hi, There was some problem with our system so I re-installed the server with CentOS 7. Now, when I am trying to run 'fdisk -l' command, it is returning a broken output. It throws this error- "fdisk: cannot open /dev/sdc: Input/output error". There are valid /dev/sdd and /dev/sde devices which are mounted and they are accessible but, somehow /dev/sdc is having a problem and

Hi, I'm currently teaching Linux system administration to a class at the local "chambre de commerce". The course is based mainly on a minimal CentOS 7 installation. Usually my preferred tool for handling manual GPT partitioning is gdisk, which is not installed on a minimal install. I just gave the good old fdisk a spin, which enables GPT partition table creation with the
