similar to: [PATCH] Ignore unfragmented file checks in defrag when compression enabled

- Add incompat flag, otherwise btrfs-progs will report error when operating on btrfs filesystems mounted with lzo option. - Allow to turn on lzo compression for defrag operation: # btrfs filesystem defragment -c[zlib, lzo] <file> Note: "-c zlib" will fail, because that''s how getopt() works for optional arguments.

I noticed a few days ago that btrfs fi defrag -cXXX can not be used to compress files unless they are fragmented. The attached patch passes the compression flag to should_defrag_range, where it disables the adjacent-extent and extent size checks if set. The inline/sparse extent check is not modified - I assumed it would not be useful to compress inline extents. -- Andrew Mahone andrew DOT mahone

We need such a sanity check for wrong start when we defrag a file, otherwise, even with a wrong start that''s larger than file size, we can end up changing not only inode''s force compress flag but also FS''s incompat flags.

Hello! I''ve a ubuntu server running over a HVM DomU. After a hang, the domU doesn''t start again. The domU was not able to mount the virtual machine disk so I started with a live cd and I tried to mount the disk root part / with no success so I ran fsck.ext3 and it gave me input/output error in the domU and in dom0 the kernel says: Feb 14 18:22:28 scofield last message

WARNING: This is not compatible with the previous lz4 patchset. If you''re using experimental compression that isn''t in mainline kernels, be prepared to backup and restore or decompress before upgrading, and have backups in case it eats data (which appears not to be a problem any more, but has been during development). These patches add lz4 and lz4hc compression

[sending this to R-devel, since it may be of general interest and could possibly lead to better instructions in the "R-exts" manual] Is this another case where only .Call() or .External() [or a fudge factor] solve my problem? Following situation: I use dyn.loaded C code to compute a recursive tree structure from my data. Beforehand I don't know how big the tree will

In support of the recently added capability to remount with lzo compression, provide a helper function to check the compression INCOMPAT flags when remounting with lzo compression, and set the flags if necessary. Also, implement the new helper function when defragmenting with explicit lzo compression and when setting the default subvolume. Signed-off-by: Mitch Harder

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

Dear all, I get a strange error when I find polychoric correlations with the ML method, which I have been able to reproduce using randomly-generated data. What is wrong? I realize that the data that I generated randomly is a bit strange, but it is the only way that I duplicate the error message. > n<-100 > test.x<-rnorm(n, mean=0, sd=1) > test.c<-test.x + rnorm(n, mean=0,

Hi: I have encountered problems with imodwt and universal.thresh.modwt and cannot find any reference in R Search. Hope someone can give me some ideas: Starting with modwt.la8 <- modwt(xdata, "la8", n.level=6) <-- this seems to work fine (1) ydata <- imodwt(modwt.la8) will always give ydata as numeric(0) (no values) instead of being a time series data with

Hi all - The following 9 patches add more error handling to the btrfs code: - Add btrfs_panic - Catch locking failures in {set,clear}_extent_bit - Push up set_extent_bit errors to callers - Push up lock_extent errors to callers - Push up clear_extent_bit errors to callers - Push up unlock_extent errors to callers - Make pin_down_extent return void - Push up btrfs_pin_extent errors to

Dear R users, I have a data frame with a few thousand rows and several hundred numeric columns (plus a date column). For each row (day), I want to assign +/- 1 to the highest X absolute values, 0 to the other values, and save all that in a separate data frame. I have a working solution (below), however I find it rather slow. Is there something I could do to increase the speed? (The code is

I've installed the printer on both boxes. On one I get a "unable to

Hi, I'm trying to use mars function in R to interpolate nonlinear multivariate functions. However, it seems that mars gives me a fit which uses only very few basis function and it underfits very badly. For example, I have tried the following code to test mars: require("mda") f <- function(x,y) { x^2-y^2 }; #f <- function(x,y) { x+2*y }; # Grid x <-
