I have it installed in VM - CentOS 7, now 8. This setup worked OK for 
many years. But I have only a few users, just with big mailboxes.

On SAS drives it works fine. The only longlock I saw was during the 
replication - I suppose transferring 20.000 big messages at once per 
mailbox could cause it. But in normal usage I don't see it.

The cause of my problem was my ignorance regarding how rolling 
replication works in cyrus. It works OK now :)
