The test for febootstrap-to-initramfs' --nocompress option was always failing for me on F11. Here's why: $ bash ~/w/co/libguestfs:210-comment-fix $ t=`febootstrap-to-initramfs 2>&1` [Exit 1] $ if ! echo $t|grep -sq -- --nocompress; then echo not found; fi not found Notice: without quotes, the [--...

In btrfs if we mount with "compress" we have no way to disable compressing by remounting (mount -o remount /mnt/btrfs), only by unmounting and mounting without "compress". This patch adds "nocompress" mount option which can be used to remount the filesystem without compression: # mount -o remount,nocompress /mnt/btrfs This option is usefull in cases when we have a filesystem mounted with "compress" and we want to disable compression but we don''t want to umount and mount...

Hello, I''m currently trying to understand how compression in btrfs works. I could not find any detailed description about it. So here are my questions. 1. How is decided what to compress and what not? After a fast test with a 2g image file, I''ve looked into the extents of that file with find-new and it turned out that only some of the first extents were compressed. The file was

Hello, is it possible to set nodatacow on a per-file basis? I couldn''t find anything. If not, wouldn''t that be a great feature to get around the performance issues with VM and database storage? Of course cloning should still cause COW. Thanks, Ralf-Peter -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to

...s idea through, this means that you would need to be able to both override each of the default mount options from the mount command (or fstab). For example, if a subvolume has its default mount option set to compress, you should be able to disable compression if you manually mount it with "-o nocompress". If mount default mount options were able to be configured through btrfs for each subvolume, then for the case when you have a simple USB drive that you''re using for backups, the default subvolume could have compress automatically set when its plugged into a PC. Then you can use sn...

Hi, I want to be certain that my apache and varnish logfiles are in strict date order when rotated. I'd like to run a sort command against them before they're compressed. I've had a look at the logrotate man page, and it looks like I can use a postrotate/endscript to do this. However, I can see any reference in the documentation for how to operate on the file. All the examples

I am not sure how to correctly troubleshoot this. I just noticed that my /var/log/xferlog file is huge. There are no files in /etc/logrotate.d/ for xferlog. This is what leads me to believe that it isnot rotating. Or perhaps I do not have it set to rotate. I am not sure. I am running CentOS release 5 (Final). Can someone tell me what I, apparently, do not have configured correctly. Thank
