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

It seems to slow on fsync(3) I didn’t see the issue with nano editor. -- Deepak From: Deepak Naidu Sent: Wednesday, April 12, 2017 2:18 PM To: 'ceph-users' Subject: saving file on cephFS mount using vi takes pause/time 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. -- Deepak ________________________________ This email message is for the sole use of the intended recipient(s) and may contain confidential information.
