I’m also getting the “Transport endpoint is not connected”. The filesystem seems to mount fine, but I can’t access the files on it?! Also, no core files anywhere on the system.

Yes, the DDUP store is on a NTFS filesystem… Using the HamsterDB backend, LessFS 1.5.8 on Debian Sid.

Any hope of getting the data back?

http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/sys-fs/lessfs/files/lessfs-implicit-declaration.patch?revision=1.1&view=markup

you should really declare each function you use and not depend on implicit declarations becasue this may lead to ugly results in x86-64 architectures.

Consider merging this patch on upcoming releases. Thank you

one more vote for ACL support (xattrs would be nice too, but ACLs are indispensable for me).

OTOH, xattrs would be a viable substitute for ACLs in my case, because rsync –fake-super can write ACLs to xattrs.

here is my patch (NOT thoroughly tested):

Here is the stack, from the bottom up.
Disk
XFS
LessFS
GlusterFS (3.0.5) <– problem child wanting the extended attributes.

Here is what I am going for.
http://www.batbuilds.com/~adam/layout.png

Could I beg and plead for you to add support of extended attributes?
