similar to: [PATCH] Btrfs-progs: make scrub IO priority configurable

I hit a problem that i can not start scrub when i am trying to track superblock generation mismatch problems. The fact is that we are trying to check whether we have started a scrub operation in userspace, this will make us can''t start scrub if that record file is damaged itself. By adding a option to skip that check, everything will be fine. Signed-off-by: Wang Shilong

This is the next patch series for scrub userland tools. Change log v1->v2: - commands now reachable as "btrfs scrub ..." instead of "btrfs filesystem scrub ..." - ability to scrub a single device instead of a whole file system - superfluous command line options removed - resume is now a separate command ("scrub resume") instead of "scrub start -r" -

The following series implement a way to generate the help messages and the btrfs man page from the sources comments for the "btrfs" commanda . The syntax and the detailed help of every subcommand are stored in the comments before the function which implements the subcommand. The fact that the help messages and the man page are generated from the same source should help to avoid

Some time ago someone posted a nice script to monitor HTB classes, classmon.pl. A friend of mine ported it to CBQ, and attached is the result. Suggestions are welcome.

Hi all, the commands "btrfs filesystem show" and "btrfs device scan" look at the /dev directory (and it subdirectories) for every block devices. This is a slow process because floppy and cdrom are also checked. Moreover, as highlighted by Helmut, if udev is not used, the /dev directory is populated by high number of non-existant devices, which slow the process. My patch

Hi all, enclose a patch to improve the "btrfs subvolume find-new" command. This is a RFC because it is not finished, but it is an usable state and may be discussed. The aim of this patch is: - take in account not only an update of the extent but also an update of the inode and xattr (which includes the acl) - extract the generation reference number directly from a snapshot The new

I have about 40 SCO 5.0.5 servers on which I am installing samba (I've tried 2.0.3 and 2.0.7, I'm having the same trouble with both). For my example, assume the following: NT domain: ORLANDO_ADMIN NT PDC: ORLANDO_PDC NT user: Administrator (I have tried other users as well) samba server: CLASS guest account (on UNIX server): nouser A generic Unix account exists called samba.

"btrfs subvolume list" gets a new option "--fields=..." which allows to specify which pieces of information about subvolumes shall be printed. This is necessary because this commit also adds all the so far missing items from the root_item like the received UUID, all generation values and all time values. The parameters to the "--fields" option is a list of items to

Hi Everyone, When you want to use ionice to limit the amount of disk a DomU has, due to have to run ionice on every blkback process? Incidently, what is the format of the blkback process? I see the following in ps aux: blkback.xx.xvda blkback.xx.xvda1 blkback.xx.xvd where xx appears to be the domain ID. I''m curious as to the last few letters mean? Thanks

Dear List, We have noticed a variety of reproducible conditions working with sparse files on multiple servers under load with CentOS 6.4. The short story is that processes that read / write sparse files with large "holes" can generate an IO storm. Oddly, this only happens with holes and not with the sections of the files that contain data. We have seen extremely high IO load for
