Read Reiserfs From Win32 !

MarkWPiper · 08-09-2005, 11:05 AM

Reiser4 support would be interesting, but isn't in the immediate future. I realized getting into the project that Reiser4 would be taking over soon, but the project wouldn't have been feasible in a 3-month timeframe with Reiser4, in part because there is very little documentation of the on-disk structures, and in part because it is significantly more complex than Reiser3 (which is in turn, significantly more complex than Ext2).

The Namesys whitepaper describes it in some detail, but the overall on-disk structures are fairly different than Reiser3. That said, concept of a keyed B* tree remains the same, so I think a a simple read-only port should be possible if I have the time to devote to it (I'll be starting my first full-time job in a month).

The last thing about Reiser4 is support for all of its advanced features, like plugins, and files-as-directories. Just as the Reiser developers are struggling right now with Linux VFS integration of their FS, the Windows IFS really isn't suited for those concepts, and they would almost certainly be unsupported.

Wow, you really seem to know your stuff

I think a read-only support would be a very good start. The times I've been in desperate need of reading linux disks under windows, have always been precisely that: I've been in need of reading. Anyway, I think a reiser4-read-only-driver would be much appreciated. Thanks for your good work; keep it up!

Hello. I have attempted to read my reiserfs3 drives with YAReG, ReiserDrive, and the rfstools - but they cannot be detected..

I am running Slack 10.1-current and my partition is as follows: /dev/hde1 [ext3,boot], /dev/hde2 [ext3], /dev/hde3 [reiserfs,this is what i want to access], /dev/hda4 [2gb swap]... windows detects the whole drive (hde) as HardDisk0, Partition1 [and sees all of the drive's space, but not the partitions on the drive]

Oh, to note, it's hde because it's on a magic ide100 pci card

would you guys happen to know why windows isn't seeing the partitions and seeing them all as 1 large partition?

Hmm... you're not using lvm or anything like that?

nope. plain....

Code:

/dev/hda1 has bootable ntfs partition, windows
/dev/hda2 has fat32 partition, data
/dev/hda3 has 1gb linux swap
/dev/hde1 has bootable ext3 partition, slack 10-1 current kernel 2.6.12-3, no udev
/dev/hde2 has reiserfs partiton, what i want
/dev/hde3 has 1gb linux swap

windows sees /dev/hde as 1 large unknown partition
windows also sees /dev/hda3 as a unknown partition

i have my bios booting hde first [which as lilo, which then can choose between hde1 and hda1

....

Mark,

Any ETA on the final version? It still says august 9 on Sourceforge. The primary reason I ask is that after enabling the rfsdfd service if I try to access the reiser partition it simply reboots the system on win2k. That is probably just the service failing (I think that is the default behavior on win2k and haven't changed it) but I'm hoping the service doesn't crash in the final release :P

It looks very impressive and I look forward to following your work.

For me, RFSGUI works best (no .NET needed and it just work out of the box)

but that can be me [
