+++ This bug was initially created as a clone of Bug #1022795 +++ Description of problem: Disk alias recycling in web-admin portal Version-Release number of selected component (if applicable): 3.2 How reproducible: Always Steps to Reproduce: 1) Create VM with single disk. (Disk Tab shows disk server_Disk1) 2) Add another disk. (Disk Tab shows disk server_Disk1 and server_Disk2) 3) Delete orginal disk (Disk Tab shows disk server_Disk2) 4) Add another disk (Disk Tab shows disk server_Disk2 and server_Disk2) Actual results: (Disk Tab shows disk server_Disk2 and server_Disk2) Expected results: Disk creation dialog provides warning and does not permit two disks of the same alias. Perhaps suggests new alias based on an incremental counter.
It seems that alias recycling doesn't consider Disk1 alias ever again, after it was initially removed. i.e. after adding Disk1 and Disk2, and then removing Disk1 the alias suggested will be Disk3, and not Disk1. That doesn't happen with other aliases, i.e. adding Disk1, Disk2 and Disk3 and then removing Disk1 and Disk2, will afterwards suggest Disk2 as the new disk alias, but not Disk1. If the Disk2 was added, then the next suggested alias will be Disk4 etc. Also if the Disk1 was used instead of the suggested name, then the next time the suggested name jumps to the last number+1, disregarding the lower numbered options, i.e. if after adding Disk1, Disk2 and Disk3, and removing first two you modify the name to Disk1 (instead of the Disk2), then the next suggested name will be Disk4, and NOT Disk2 again.

oVirt 3.5 has been released and should include the fix for this issue.
