If you are using GRUB 0.97 (legacy GRUB), then this capability is provided by the "default saved" and "fallback" commands.

Apologies if this should be well-known, but I couldn't find anything! Situation: a system in a remote location, with no KVM, IPMI or iLO, and therefore no console access, only ssh. Multiple kernels listed in grub.conf. Is there a way to reboot temporarily into one of the other kernels listed in grub.conf, without changing the default= line, so that a subsequent reboot will default back to

There's grub 0.97 on CentOS 5. The manual at http://www.gnu.org/software/grub/manual/html_node/index.html says it is for 0.97. However, it mentions for instance a program grub-set-default that is not present in grub-0.97-13.2. It also mentions grub.conf options savedefault and fallback. Are these available in the CentOS grub? I tried with savedefault and it does not create a

Nice catch, Mr. Schumacher ---> The following modules are included as standard with release 1.831 of Webmin. FirewallD firewalld.wbm.gz Configure a Linux firewall using FirewallD, by editing allowed services and ports. This is likely the right tool for the job.

Hi, This is slightly offtopic, but I have been trying to resolve that problem for two days now without much success. It looks like this may be something that works with CENTOS5, but not with CENTOS6! I have two machines, fileserver1 and server5. fileserver1 runs on CENTOS6 (virtualized, if this is important), server5 runs on Centos5. Both are running with the most recent updates. Server5 is a

Hi, I updated a server yesterday from "kernel 2.6.18-128.7.1.el5xen" to "kernel 2.6.18-164.el5xen" After rebooting, my message log is flooded every second or so with this error messages: Oct 6 14:52:20 xenserver1 kernel: EDAC MC0: UE row 0, channel-a= 0 channel-b= 1 labels "-": NON-FATAL recoverable (Branch=0 DRAM-Bank=0 Buffer ID = 0 RDWR=Read RAS=0 CAS=0

hi! I got a problem with one of my servers where the boot process fails, because it cannot find its root partition. My /boot/grub/grub.conf uses to look like ---8<--- title CentOS (2.6.32-431.17.1.el6.x86_64) root (hd0,0) kernel /vmlinuz-2.6.32-431.17.1.el6.x86_64 ro root=UUID=8ef1f6cb-5dfc-497e-83d0-8d91cbbe4939 rd_NO_LUKS LANG=en_US.UTF-8 rd_NO_MD quiet

There are 3 issues here: Grub, the kernel and RedHat. 1) Grub won't run in an XFS /boot partition, but will happily run xfs_state1_5 to boot from an XFS root partition. 2) The kernel has supported XFS quite happily since at least 2005, I am looking at an SGI Propack 4 manual of February that year and it states that SLES 9 SP 1 contains the kernels with XFS support. 3) May be an issue.

I think performance is not just about your xml, the host system will have a bigger impact.

hi, I am planning to replace my old CentOS 6 mail server soon. Most details are quite obvious and do not need to be changed, but the old system was running on spinning discs and this is certainly not the best option for todays mail servers. With spinning discs, HW-RAID6 was the way to go to increase reliability and speed. Today, I get the feeling, that traditional RAID is not the best option for
