Xen box down
My stock CentOS 5.4 box won't come up after a reboot as reported from my office. Error is: "duplicate or bad block in use" Before rebooting xm dmsg had printk suppressed messages. The box is remote, 2 hour drive. Some advice on what hardware to bring with me and how to approach this via fsck would be welcome. Its an nvidia dmraid boot on WD Velocirapters. And Happy New Year to

Mounting LVM contained ntfs systems.
Using CentOS 5.4 Xen Virtualization "stock install" Added rpmforge NTFS extension for mount command. Scenario: Have mirror dd'd off to "backup" unmounted LV contained Windows machine. Within the LVM volume are two NTFS partitions formatted by Win2k8. Issue: How can I mount this? I need to verify file existence and run batch of file compare checks. If I try to mount

Move Windows within an LV to another pv safely
----- "Ben M." <centos at rivint.com> wrote: > Does this appear to be a sound procedure? I have one inline question. I read your version of the procedure and it looks like you want to skip the pvmove. That's fine, but it means more downtime (an unreliable estimate is one minuted per GB). In that case, you don't eve...

Slightly OT: FakeRaid or Software Raid
I have had great luck with nvidia fakeraid on RAID1, but I see there are preferences for software raid. I have very little hands on with full Linux software RAID and that was about 14 years ago. I am trying to determine which to use on a rebuild in a "standard" CentOS/Xen enviroment. It seems to me that while FakeRaid is/can be completely taken care of in dom0 dmraid whereas with

Xen Database vms
Are "centralized" database (SQL) servers best left out of virtualization and committed to their own hardware like the "old days" or are there some guidelines one should consider in setting them up? I'm not talking mega-large recordsets, but large enough to handle multiple years of CRMs and intensive querying, Accounting Systems and so forth. Fundamental website CMS

Slightly OT - Grub fallback option
Does anyone have a standard install of CentOS virtualization grub.conf working in a proven state with the FALLBACK option? If so, can you post your grub.conf? I mistakenly updated to 5.5 and am concerned about nvidia driver comments in the release notes. I did not have protectbase configured on this machine. It is a remote device that will reboot.

Lockup with (none) login
I had a CentOS 5.5 Xen "standard virtualization" install lockup on reboot after an battery backup (apcusbd) orderly shutdown induced by a power outage. It may have been sitting with two kernel updates without a reboot. I have to head to the site (with a fractured ankle), but reports indicate that it is at - (none) login: which only returns back to itself after a user login at

Power Management and dom0 cpus
["Standard" CentOS 5.5 Xen Virtualization installation.] I'm setting up a new box on AMD Opteron platform. I'm doing some preliminary baselines (no domUs running) with an inline Watt/VA meter. It appears to enable full power management Xen dom0 must have all cpus by not limiting in kernel statement nor in xendconfig.sxp. In previous installations I cut them back to 1 or 2.

Package updates and "required" reboots
I still operate under the assumption that glibc and kernel updates "require" a reboot to be prudent on a Linux OS. With CentOS Xen 5.6 (standard installation, SELinux enabled) is there an FAQ or general user consensus as to when to do a reboot after what updates?

Arp Flip Flops make machine inaccessible.
CentOS 5.5 Xen "standard" Xen Installation. I have two nics. I just put the second one to DHCP and modified the ifcfg-et01 and so far I am holding, but I am not confident. Prior they were sequential IP Addrs on same subnet. arpwatch has indicated flip flips. I can find no rhyme or reason to predict them. I know I missed I must have missed a step somewhere. I want to keep the
