Hi all, Fewer days ago a CentOS box server suffered a manual and unexpected reset (too large to explain: there are silly people in everywhere). The result was the system did not mount de root (/) partition and the boot process was stopped. I repair it easily: boot from LiveCD (Knoppix in my case), umount root partition and pass the e2fsck utility. Because of that I've used several fs tools

I have just been thru rebuilding a server that had been suffering severe performance problems. I transferred the partitions to another hard drive, copying into freshly formatted filesystems. This made a HUGE difference in performance. One key directory structure stores email messages in an structure where there is a directory for each mail account, and the messages are stored in

Hello everybody, reading about the speed improvements possible with (on boot) preloaded files (which should be continuous on disk) I searched for a ext3 defrag program. I found an ext2 defrag program (http://www.ibiblio.org/pub/Linux/system/filesystems/defrag-0.70.tar.gz, available in debian as defrag) which would have an optimal feature (moving files by a list) but refuses to work on ext3.

If you are using XFS - there is mount option "discard|nodiscard" From XFS man page: discard|nodiscard Enable/disable the issuing of commands to let the block device reclaim space freed by the filesystem. This is useful for SSD devices, thinly provisioned LUNs and virtual machine images, but may have a performance impact. Note: It is currently

I have used restore to restore a snapshot of home data.

hi, I have two machines, machine1 and machine2 both in the same network. The command I have been using to install a paravirt guest is virt-install --name=test --ram=512 --vcpus=1 --file=/dev/vgraid/puremessage-vm-root --paravirt --location=http://mirror.centos.org/centos-5/5.2/os/x86_64/ In machine 1 it is working. But not in machine 2. It is not able to retrieve or access url in machine 2.

Hi, I hope I''m right here. If not then please point me in the right direction. My problem in short: I have problems using (pinning, mmu_update) physical pages from 0x900000 to 0xB1000 usualy. I''m writing my own little amd64 64bit toy kernel (based on Mini-OS as starting point) for xen and I run into problems with the way the start of day sets up the physical pages. My kernel

You're right, there's a procedure following it, once the space is zeroed qemu-img will recognize it as such and will eliminate it when 'convert' is used. Apparently Fedora qemu has some better capabilities to shrink partitions but they haven't made it to "long term support" distributions yet. For now, what has to be done to shrink qcow[2] partitions (raw works) is

Hi, I''m trying to use the SYSCALL/SYSRET opcodes with a minios kernel without much success. Going by the manuals (and linux sources) I first have to setup the STAR and LSTAR registers to define the segment and instruction pointer to be used for SYSCALL: /* * LSTAR and STAR live in a bit strange symbiosis. * They both write to the same internal register. STAR allows

Hi, If i set strict allocate = yes in samba to speed up the transfer of a mssql database dump, then btrfs does not compress the file. I have tried it also by just copying a small file in Windows to the samba share and the same. I have tried btrfs mount options autodefrag and then btrfs fi defrag -c and the file still does not get compressed. I have tried kernels 3.6.11, 3.8 and 3.10.7 on FC16

Hi, maybe I'm missing something fundamental but I can't seem to be able to build a custom kernel-image.deb for xen. I was able to build the linux-2.6 with xen images from the repository and build a vmlinux file using the directions from upstream Xen. But I've had no luck with make-kpkg. Can anyone give me some hints? MfG Goswin

Hi, has anyone build a linux-2.6.16 deb that can be used to compile xen? The default unstable package does not seem to have any xen patches included, only the /debian/arch/amd64/xen dir for the .config files. MfG Goswin

i am having problems installing direct x i have followed the guide http://www.linux-gamers.net/modules/news/article.php?storyid=2334 the only problem is it doesnt work in steam it still says you need direct x 8.0 of greater i dont know if this is helpfull but it never tells me to reboot after direct x installation so i assume it is not installing properly i will hapily post any log files anyone

Two files in the different subvolumes may have the same inode id, so The rb-tree which is used to manage the defragment object must take it into account. This patch fix this problem.

Kernel 3.1-rc8 btrfs-progs-0.19 mount options: noatime,autodefrag (space_cache is enabled) There are snapshots present on the filesystem. When I do a btrfs fi defrag on a file, the file becomes much more fragmented. The end result can be a file with 20k times more fragments than before. Initially I thought the extents were just smaller but were next to each other, so I checked with both

Hey folks, Does anybody know if any of these are on the roadmap for ZFS, or have any idea how long it''s likely to be before we see them (we''re in no rush - late 2008 would be fine with us, but it would be nice to know they''re being worked on)? I''ve seen many people ask for the ability to expand a raid-z pool by adding devices. I''m wondering if it
