mr biglebowski you have been very glad on your answer
actually after two weeks of intense pressure we got the fixing for that.
I will post the problem and solution maybe one day some one could get benefit from it.
its an ASC EVOIP passive recorder, getting packets from a Siemens PBX both RIAA(normal phones and MTB (trading turrets)
I added a new NAS (NAS2) to an ASC EVOIP system which had a NAS1 which was more than 99% full. I added the new NAS as NAS2, disable an enable the archiving job, (cascading mode which means used all the media in sequence) and waited.
Days after, the NAS2 is empty, and the system keeps showing the error of "NAS1 is full"
the answer was "work as designed" so I could be a bug for some points of view.
cascading mode does not apply to NAS, only to removable media (like DVD-RAMs)
So we got to copy all the file estructure manually from NAS1 to NAS2 replicating shared folder user and pass.
the installer who added NAS1 did it with a IP address path rather than a hostname path.
So we got to erase the IP address of NAS1, put that address to the NAS2, later get another IP address for NAS1, effectively the archiving service should be disabled while configuration changes are done, later restarting the archiving, operation completes.
pd - the reason for my NAS2 to no write was that i had a subfolder named backup, the system detected it as a unknown contente and disable writing to prevent accidental loss of data (good feature indeed, but kind a desperation when you don't know the why)
pd - the path to the recordings is stored on the Database, so a change in the NAS names / IP would lead to lose access to the recordings archive.
Thanks again.
