1. you've deleted the storage side, just destroy the domain? 2. the error has nothing to do with remove domain, it failed validating access to the mount. Is it possible that you removed the export from the server? (In reply to Ayal Baron from comment #1) > 1. you've deleted the storage side, just destroy the domain? I did destroy the domain, there is no problem to destroy - this bug is on text only (internal engine error pops up for the user). > 2. the error has nothing to do with remove domain, it failed validating > access to the mount. Is it possible that you removed the export from the > server? the validation happens when we try to remove the domain, and yes, I did remove the domain in the storage. we already have a "domain does not exist" error when we validate mount during create domain so if we validate during remove we should probably have a "domain does not exists" as well instead of internal engine error message. The problem is that the connection error is "swallowed" in RemoveStorageDomainCommand. The connect() method (from one of the storage helpers) is called from executeCommand, however it returns only boolean without the actual result, thus not setting any error code/fault in the return value of the command, so the command just reports setSucceeded=false without any further details - resulting the generic error. User can 'destroy' the domain from the GUI |
