Ceph » CephFS

A dev node created on a cfuse mount is displayed correctly by ls -l on the same mount point:

crw-rw-rw- 1 root root 1, 3 May 29 2010 /media/shared/backup/phone.bak/dev/null

however, with the same ceph filesystem mounted with the kernel client (tried 2.6.35 and 2.6.38, on x86_64-linux-gnu and mips64el-linux-gnu), I get:

crw-rw-rw- 1 root root 0, 259 2010-05-29 09:52 /media/shared/backup/phone.bak/dev/null

I first noticed this after rsyncing onto a kernel client mount point, and then rsyncing again onto the cfuse mount point. The problem occurs (as expected) in both directions.

I don't know which one was supposed to be correct, but clearly the other needs adjusting to match the on-disk representation.
