However, using dsync to make a mirror throws a lot of errors like below. # dsync -v -u recover -o "mail_plugins=zlib" mirror dbox:~/ndbox dsync(recover): Error: corrupted lz4 chunk at 43551 dsync(recover): Error...

recover should send messages to stderr, not stdout
Hi, recover() sends all its messages, which I consider to be error messages, to stdout. I think they more properly belong to stderr. This is an important difference for those of us who use R in batch mode to generate ASCII files. Thanks, Vadim [[alternative HTML version deleted]]

data recovering in EXT3
...ot;fsck -y" on one of our raid disks (with ext3 file system). After that we have found that SOME files disappeared (they are not seen in the directories where they have been before). The data are extremely important and contain a lot of programs, scripts for some data analysis and very hard to recover by hands. I have run ''fsck -y" once more and it recovered just few files.. Is there any way, any tool that would allow to recover the data? Probably there is some specific options for the recovery ralated with journaling in ext3? I have used debugfs, it produced following, if it help...

'options=utils::recover' not working in .Rprofile or within R
For years I have been using options(error = recover) either in .Rprofile or from within R for debugging purposes. The functionality of this appears to have changed and I can't recover it (no pun intended) using the ?options help page. How can I get the old functionality back, particularly from within .Rprofile? A specific line entry would be app...

recover() (PR#8546)
After using options(error=recover), it takes a long time (too long) to get back to the prompt. Look at: Browse[1]> recover() Enter a frame number, or 0 to exit 1: window(test, start = c(15, 1), end = c(17, 1), extend = TRUE) 2: window.ts(test, start = c(15, 1), end = c(17, 1), extend = TRUE) 3: as.ts(window.default(x, ...)) 4...

Problem setting options(error=recover) in my
I'd like to be able to set options(error=recover) in my file. When I do this I get the message "Error in options(error = recover) : object "recover" not found I assume this is because the utils package (where recover and dump.frames are defined) has not been loaded at the time I make this call. I suppose I could e...

Exit status of Rscript when setting options(error=utils::recover)
Hello, I've noticed that Rscript didn't exit with error code if I set options error = utils::recover in .Rprofile . for example Rscript -e "asdf" Error: object 'asdf' not found No suitable frames for recover() echo $? 0 if didn't set options in .Rprofile, Rscript exit with error code 1, is this expected behavior ?

Exit status of Rscript when setting options(error=utils::recover)
Thanks for explanation, so recover in non-interactive session exit with 0 is expected behavior . dump.frames said that it always write to file (workspace , or specified file). I have a R script run as a auto build stage, so I want to print detail backtrace to console (with source file, line number) for quickly debug, without savin...

Recovering LVM volumes
...Both were LVM volumes with three or four physical disks, with ext3 fs. One disk, maybe even the boot one may even be missing, either from one or both sets and we do not know the disk order. I got these left from an earlier sysadmin who left the company & nobody know what's what. I need to recover data so I need to backup each of the disks to a disk image file first, then find block-size/recover lvm metadata on the volume, mount the volume to my current server and recover whatever files can be recovered manually. My question is: - what switches to be used with dd in creating the image, so...

How to recover t-statistics?
Hi! I'm doing Monte Carlo analyses of the distribution of the t-statistics of the parameters of models evaluated with the lm( ) function. Is there an easy way to recover the t-statistics (similarly to using coef to recover the coefficients)? Thanks, joseph --------------------------------- [[alternative HTML version deleted]]

options(error=recover) in .Rprofile
Hi, I'd like to try using "options(error=recover) in my ~/.Rprofile, but it appears that the function "recover" is not defined during R startup when the .Rprofile is processed. "recover" is defined after I get an R prompt, however. Can anyone shed light on why this is, and whether a work-around is possible? I've...

[PATCH 1/1] Patch to recover orphans in offline slots during recovery.
In the current recovery procedure, recovering node recovers orphans from the slot it is holding and the slots that dead nodes were holding. Other online nodes recover orphans from their slots. But orphans in offline slots are left un-recovered. This patch queues recovery_completion for offline slots. Signed-off-by: Sri...

recovering corrupt file system
Any recommendations for tools to diagnose and recover problems on an ext4 file system? In particular: root@jessie01:~# mount -o ro /dev/markov02/root /mnt/markov02 mount: wrong fs type, bad option, bad superblock on /dev/mapper/markov02-root, missing codepage or helper program, or other error In some cases useful info is found in syslo...

[PATCH 1/1] Patch to recover orphans from the slot during mount
Currently we only queue recovery during mount if the journal is dirty. If the last node holding orphans in other node's orphan directory dies and is the first one to mount then it only recovers its orphan directory which leaves the orphans in other nodes slots. Since the other nodes journals are clean they will not queue to...

Recovering btrfs fs after "failed to read chunk root"
...boot so I turn it off after some minutes and restart. Now it comes the fun: btrfs: allowing degraded mounts btrfs: disk space caching is enabled btrfs: failed to read chunk root on sdb1 btrfs: open_ctree failed From this point I found no way of accessing my data. Nothing works, including mount -o recovery and even btrfs-restore. I find this discussion: So I tried several times with btrfs chunk-recover: If I keep all the disks, it goes like this: [root@tambura btrfs-progs]# ./btrfs chunk-recover -v /dev/sdb1 > log_2.txt All...

recover user error
ZFS claims that it can recover user error such as accidentally deleting of files. How does it work? Does it only work for mirrored or RAID-Z pool? What is the command to perform the task? Also for COW, I understand that during the transaction (while data is been undated), ZFS keeps a copy of the previous data. However, once th...

recover and "called from" information
Hello, When using recover, the called from information is always "eval(expr, envir, enclos)", which is not particularly useful. > f <- function( ){ g <- function(){ stop( "ouch") }; g() } > options( error = recover ) > f() Error in g() : ouch Enter a frame number, or 0 to exit 1: f(...
