Hello everyone, it’s me again.
I have run into an issue where when I start a replication of a share from one rockstor appliance to another it will fail after three successful replications. Failure on the receiving machine is something like “Failure to promote oldest snapshot to share”.
I have searched through the forum and found some threads and github issues touching this problem and some solutions that where proposed there.
I’m tagging @phillxnet directly because I can reproduce this issue with at least one share.
So far I tried disabling quotas on the receiving pool, which did not work.
I tried making the snapshots on the receiving machine RW which also did not work.
I did not modify any of the existing python files und /opt/rockstor/src/rockstor.
If error logs or logs in general are requested I will try to provide them as fast as possible. I didn’t want to clutter the starting post with unnecessary text.
What may be of notice is that the receiving machine is completely LUKS encrypted.
Addendum: I also noticed whenever I try to delete a share I get an error with “device is busy” but the share is still correctly deleted. I believe I read somewhere this is also related to quotas.
Addendum 2: I also noticed that with Replication my transfer speed seems to be capped at around 1GBit for networking although i have 10GBit available. A test with rsync tells me I’m at around 2GBit (which is what I would expect for HDDs R/W speed)
