Hi Cephers,
Why it is use journal with Filestore ? From my understand, it is used to
prevent partial write.
In my view ,it is needn't journal for Filestore as to the scenario for EC
backend and for RGW object storage application.
For EC backend, it just now only have write full and append
HI,
There is requirement from customers that need to continuous backup rbd image
to backup device or another ceph cluster.
As far as I know , rbd journal can be used to record all the rbd mutations
to journal which is stored in rados objects in the same ceph cluster
Is it has interface to push
] ? Am I right?

HI All,
Why it is needed an entry of journal t is aligned by CEPH_PAGE_MASK ? For
it causes the data of journal write are amplified by 2X for small io
For example write io size 4096 bytes, it may write 8192 bytes
prepare_single_write 2 will write 98304 : seq 24 len 4324 -> 8192 (head 40

I’m testing the deep-scrub function of ceph. And the test steps are below :
1) I put an object on ceph using command :
rados put test.txt test.txt –p testpool
The size of testpool is 3, so there three replicates on three osds:
osd.0:
