[PATCH] [v2] WIP: ddrescue mapfile filter
This allows to overlay bad sectors according to the mapfile generated by
ddrescue, to then see where sectors are used using fsck and trying to
copy files around.

[PATCH] [v3] ddrescue mapfile filter
This allows to overlay bad sectors according to the mapfile generated by
ddrescue, to then see where sectors are used using fsck and trying to
copy files around.
Should now be mature enough to be useful to someone else.
And we have a proper test also.

[PATCH nbdkit] ddrescue: Miscellaneous fixes.
A few fixes and a possible enhancement to the ddrescue filter. If you
think these are all OK, I will squash it into your patch and push it.

Anything for nbdkit 1.20? / ddrescue filter latest version?
Eric: Even though it's only been about 2 months, we have a very good
feature set for nbdkit 1.20. Is there anything you'd like to get in
or any patches I have missed?
Francois: you mentioned the ddrescue filter yesterday. While I don't
want to put in a new filter right before we do a release (new features
need to sit around in development so we can uncover bugs), if you do

only the first ResetCDR works after upgrade to 1.6
Hello -
I am upgrading from asterisk v1.2 to v1.6 and I am seeing a problem with
recording CDRs using MySQL. Unlike all of the other postings and web
pages I have found on this issue, my installation successfully stores
the -first- CDR, but nothing after that.
As background info, I will note that I don't use CDRs for billing, but
more in a logging fashion, to record how a given call

how2 mount ntfs partition that is part of a full HD image file
I have a full disk image file (courtesy of ddrescue), and need to mount
one of its partitions. I suppose I should have just extracted the single
partition when I was using ddrescue, but right now I have the whole disk
instead, and no disk space left to re-do the extraction (in fact I won't
be able to use the system where I did it for several weeks, so I'd love
to be able to mount just the

Using CentOS 7 to attempt recovery of failed disk
Well, I'm not a noted expert on ddrescue, but my limited experience tells
me that when it hits bad spots (or a big cluster of them) it can go very
slowly as it tries multiple times to read each sector (or track, I'm not
sure which, in this case). It keeps a list of bad spots and goes back at
the end to try again to read something from them. Of course, if you've had,
eg. a head crash,

Using CentOS 7 to attempt recovery of failed disk
I have a disk that is flagging errors, attempting to rescue the data.
I tried dd first - if gets about 117G of 320G disk and stops incrementing
the save image any more.
Now I'm trying ddrescue and it also stops about the same point
Thoughts on how to continue past that point ?
Thanks,
Jerry

logical volume is unreadable
Hi all,
one of my lv has become completely unaccessible. Every read access
results in a buffer io error:
Buffer I/O error on dev dm-13, logical block 0, async page read
this goes for every block in the lv. A ddrescue failed on every single
block.

syntax of tftpd mapfile
Hello,
I want to use tftpd rewrite feature to sort configs from different systems
to subdirs named by the system-ip and (perheps) by date.
the system (cisco pix) issues 'wr net: /config'
this should be rewritten to /10.0.0.1/config or better /10.0.0.1/20020403-1448
Is this possible?
Thanks for any hints.
