Hi,
has anybody tried using the new ploop storage for openvz images together
with moosefs ( http://www.moosefs.org/)?
ploop mount -d /dev/ploop0 /mfs-mount/root.hdd
Adding delta dev=/dev/ploop0 img=/mfs-mount/root.hdd (rw)
PLOOP_IOC_ADD_DELTA /mfs-mount/root.hdd: Invalid argument
In syslog I find:
kernel: File on FS without backing device
I thought it might be because ploop needs direct-io (right?), but
mounting with direct-io enabled seems not to be supported by moosefs:
mfsmount -o direct_io /mfs-mount
mfsmaster accepted connection with parameters: read-write,restricted_ip
; root mapped to root:root
fuse: unknown option `direct_io'
Has anybody got it working somehow? :)
Btw: I'll also post this question to the moosefs mailinglist as I'm
pretty sure the devs there might have interesting answers too.
Corin
