reiser4 partition not mounting

Hello, trying reiser4 on my system but can't get the partition to mount.

I have patched gentoo-dev-sources 2.6.7-r11 emerge reiser4progs and created reiser4 partition.

try just doing 'reiserfs' instead of reiser4. ex:

hm. I'm about out of ideas then. Off hand, the error looks like either its the wrong file system (not reiser) or there is an error in the superblock. Try mounting with autofs (mount -t autofs /dev/md3 /var/cache/http-replicator) or try remaking the filesystem.

I remember when I first installed gentoo, I had a problem gettting fdisk to read my hd. I ended up having to initialize the first 1K of the disk with 0's. I can't remember quite how I did this now. It used 'dd' and was something like:

The correct line for reiser4 is reiser4 in your fstab and mount -t. There is a bug on the not mounting issue here. In short, if you are using a new snapshot of reiser4, you also need a new snapshot of libaal and reiser4progs.

There is also a similar thread here. Gentree had the same problem in his second to the last post, but was apparently not able to fix it.

hmm, a lot of times people mispesll reiser. resier looks very similar. so if the code snip isn't a direct quote from fstab, i'd say to double check.

try:
mkdir /test
mount -t reiser4 /test
umount /test
rmdir /test

if that fails then there may be a bad superblock...

also, is it "user" or "users" for the mounting option.

I have double checked fstab and entries spellings are correct, the partion worked fine when i had it as reiserfs.

Think it may be related to issues in linked threads from oberyno post, the bug issue seems to be resolved though, i am using kernel older patch as it was the only one i could find for gentoo-dev-sources, may try the love sources but they seem to be having issues as well. Using masked reiser4progs from portage.

Will see if can find late updated kernel or try patching a vanilla kernel.

This box will be a server only doing, print,samba,scanner,rsync mirror,http-replicator so desktop performance is not such an issue though would like to get as much performance from it as possible.

Try using the nosuid in your fstab to mount the reiser4 partition. For example, /dev/??? /mount_point nosuid 0 0. Might need rw.

Did you enable large keys in the kernel? Large keys and short keys are binary incompatible, and small keys have problems( actually I'm not sure, but no one uses them; large keys are better). You should probably remake your kernel with large keys and then run mkfs.reiser4 again.
Edit: the kernel option is CONFIG_REISER4_LARGE_KEY.
