Re: [Veritas-bu] Pure Disk Pool Down -MSDP

I have had some bad experiences with ZFS under FreeNAS. I suggest that you login to the OS and see what ‘zpool status -x’ reports.

I find that when the hard disk has a bad sector ZFS cannot recover easily. If the unreadable block is written, the disk hardware will revector the bad block to a spare. But as ZFS is a copy-on-write file system, you cannot write the bad block e.g. by overwriting the file that has the bad block. The only way around it is to remove the disk from the RAID set, mount it up as UFS and then write to the block, or erase the whole disk. Then add back and resilver. I had a case where ZFS would not let me remove the disk as that did not leave sufficient redundancy. Anyhow having to do all that every time a disk has a bad sector is painful.

So, I suggest that you check that ZFS is OK as a good place to start.

Hello Geeks !

Good Day !

I am stuck in one issue -we have a pure disk pool created on ZFS file system. I am well aware that symantec doesn't supports this.

Now this was working file till yesterday but since yesterday 09:00CST it has stopped working.

# ./crcontrol --dsstat

Error: -1: NetConnectByAddr: Failed to connect to host: Connection refused (146)

Error: -1: NetConnectByAddr: Failed to connect to spoold on port 10082 using the following interface(s): [ 127.0.0.1 ] (Connection refused) Ensure storage server services are running and operational. V-454-92

Error: 53: Could not establish a connection to 127.0.0.1:10082: connect failed (Connection refused)

Error : Connection failed connection actively refused. Note that the content router needs to be running to get a connection.

Error: 25067: Database: connection to database crdb at server:10085 failed (could not connect to server: Connection refused

Is the server running on host "server" and accepting

TCP/IP connections on port 10085?

)

Error: 25053: Database Manager: could not access storage database (connection actively refused).

Error: 25004: Failed to run database class

Error: 25004: Failed to read startup mode

Error: 26016: Symantec PureDisk Content Router: Initialize failure.

I need some help here ,what should I do ?
