-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, this is a new attempt to improve the output of the command "btrfs fi df". The previous attempt received a good reception. However there was no a general consensus about the wording. Moreover I still didn''t understand how btrfs was using the disks. A my first attempt was to develop a new command which shows how the disks

I boot from the installation DVD, with an already existing CentOS 5.5 system on my hard disks. I have separate boot, root, and home partitions. I have moved the boot partition and now I need to re-initialize grub from rescue mode. Attempting to use 'rescue mode" to automatically mount my system under /mnt/sysimage eventally fails with an error message, which essentially says

Hi. I have cloned a RHEL 5.6 physical server over to a ESXi 5.0 Virtual Machine. Using a live CD on the new Virtual Machine I created 3 partition /boot (/dev/sda1), / (/dev/sda2) and swap (/dev/sda3), I then mounted the / (sda2) partition and created the /boot directory and mount the boot partition partition /dev/sda1 into /boot. I then used rsync to copy the source machine over to the Virtual

Hi Updated the firmware on a PERC RAID card as it was out of date and causing a monitoring error - Everything went fine but on the reboot the box now tells me it cant find a valid boot device - I am thinking maybe somehow the boot block on the logical disk is shot. Can anyone advise me on how to rebuild the bootloader on lilo using a rescue CD? thanks

I had to unmount the boot partition (being in Troubleshooting mode), run the above command, which provided a new UUID and at last the partition was recognized as xfs. (I forgot to copy the output to paste here.) I then mounted the boot partition again, chrooted, grub2-install'ed successfully,

Booting to CentOS 5.5 works and I am able to login with all my devices mounted. When I boot from the install DVD and type "linux rescue" I eventually get the message, after attempting to have one of the screens mount my partitions in read/write mode: "An error occurred trying to mount some or all of your system. Some of it may be mounted under /mnt/sysimage." But nothing

I'd like to rename my existing volume groups and logical volumes (I picked names a long time ago I no longer like :-). I recently stumbled across the lvrename and vgrename commands, but when I tried the former to rename the logical volume that my root partition resides on, the system became unbootable. In addition to renaming the LV (and VG if I decide to to that as well), what

Hi, I am trying to recover data from my old system which had LVM. The disk had two partitions - /dev/sda1 (boot, Linux) and /dev/sda2 (Linux LVM). I had taken a backup of both partitions using dd. Now I am booting of CentOS live cd for system restore. I recreated partitions like previous system using fdisk and then used dd to dump all the data onto it. I would like to mount sda2 as LVM, but I

Hi I have been trying to get puppet working with kickstart. I am trying to install Hadoop on the nodes. Installing puppet from kickstart work and when the machine restarts, certificates are pulled down and hadoop user is created and files are extracted. I want all the user creation etc to be done before the machine reboots so that I can set up init.d scripts to do a start of hadoop . So I

If I boot C5 from DVD in rescue mode, chroot to /mnt/sysimage, and try to do a grub-install /dev/sda it will fail because the /dev folder is empty (in the chroot environment). Until now I've then created the missing nodes manually, but is there a smarter way of doing this? Some devfs that needs to be mounted on top of /dev?

Hello list. Since morning I have an emergency. After last kernel update one of my servers didn't start. On display I see only "GRUB" :( I have 2 more servers based on CentOS too, but after the same update this servers works. All servers have 2 HDs and works as software mirror.
