Description
Ceph with ZFS
I have been working around ceph quite a long and trying to stitch zfs with ceph. I was able to do it to certain extent as follows:
1. zpool creation
zpool create -f store /dev/sda4
2. set dedup
zfs set dedup=on store
3. create a mountable volume of zfs (zfs create)
zfs create -V 10G store/str
4. format the volume with ext4 and enabling xattr
mkfs ext4 -t /dev/zd0
mount -o user_xattr /dev/zd0 /osd.0
5. mkcephfs on the volume
mkcephfs -a -c /etc/ceph/ceph.conf -k /etc/ceph/keyring.bin
6. Start the ceph service
7. Mount using ceph-fuse
8. Zfs dedup works on ceph cluster now but there is a much of layers on storage following this method which slows down the performance
