HTTP 500 on replication tasks

[sebasb (Sebastian Bordon)]

Hello, I’m on version 3.9.2.48
I’ve created two replication tasks and while both succeeded a couple of times they fail afterwards with error HTTP 500 INTERNAL SERVER ERROR. Both rockstor are at the same version.
Short of recreating them and reconfiguring from scratch I’m not sure of what to do. Sometimes deleting the last snapshot works and sometimes it does not.

I’ve found this error log

output: [''] error: ['WARNING: quotas may be inconsistent, rescan needed', '']
[30/Apr/2019 11:23:03] ERROR [storageadmin.util:44] Exception: Snapshot (Profiles_19_replication_290) already exists for the share (Profiles).

@sebasb Hello again.

From the provided log except this looks to be the known failure referenced last we spoke:

Remember we still have a fragility in the replication system re existing snapshots from prior failed replication tasks. It will indicate this as a failure if you are affected. Just delete the ‘blocking’ snapshot if you are affected by this and kick off another.

ie the:

Snapshot (Profiles_19_replication_290) already exists for the share (Profiles)

Bit.

Not very helpful I know, but that’s all I see in this bit of log.

Thanks, the HTTP 500 thought it was due to another reason. Will delete snapshots and wait to see what happens.
