Yes via creates a swap file and nano doesn’t. But when I try fio to write, I don’t see this happening.

Is it related to this the recovery behaviour of vim creating a swap file, which I think nano does not do?
A sync into cephfs I think needs the write to get confirmed all the way down from the osds performing the write before it returns the confirmation to the client calling the sync, though I stand to be corrected on that.
Ok, I tried strace to check why vi slows or pauses. It seems to slow on
fsync(3)
I didn’t see the issue with nano editor.

Folks,
This is bit weird issue. I am using the cephFS volume to read write files etc its quick less than seconds. But when editing a the file on cephFS volume using vi , when saving the
file the save takes couple of seconds something like sync(flush). The same doesn’t happen on local filesystem.
Any pointers is appreciated.
