Subject: copy / move reflink files to new filesystem / or whole fs
Date: Tue, 15 Jun 2021 07:45:59 +0200 [thread overview]
Message-ID: <CANSSxykVgGj5PHzfPm_xvJi_dpooS_vBpO14-S3KhM6BZfBFtA@mail.gmail.com> (raw)
Hi,
is there any way to copy or move data between 2 xfs fs with reflinks
on the same host, so that the data is not rehydrated (I guess cp
--reflink will not be working)? If this is not possible, would it be
able to clone the existing fs to a new one and then continue to use
both?
Background: I've backup data on a 350 TB reflink xfs fs, now a second
fs will be added to the server and parts of existing data should be
moved to it. If it's possible to clone the whole fs I could delete
parts of it afterwards, but copying/moving single directories would be
easier.
Ralf
