Yesterday I replaced a 1TB drive with a 2TB drive. The rebuild seemed to go OK I got a parity OK message after it was done. Today I tried to copy some movies to the array and received the following message from unmenu:  "Sorry, no file system detected on /dev/md5". The message came after the first movie was copied to the array and changing the parity from before I replace the drive. Now I don't know if the new drive was rebuilt with the data from the drive I replaced. What can I do? Do I just replace this drive and rebuild? Will the copy of the first movie today prevent the new drive from being restored to the way the original 1TB drive was before I replaced it?

Was the new drive precleared, how many runs?

We can't tell, since you did not provide a syslog for analysis.

 

It could be absolutely anything, from a disk failing, to a cable coming loose.

 

If the disk was successfully re-constructed from parity and the other disks, no reason another replacement cannot be re-constructed. 

 

Question is... was the original bad, or is there a different reason the disk was taken out of service?

Here is the syslog.

 

What I did was bring the array down, replace the 1TB drive with a 2TB drive clicked on the start button and checked the yes box to rebuild. After several hours the rebuild was finished and it said the parity was OK. Today I selected two movies to move to the array. The first one seemed to be copied - it was listed in Windows Explorer but the second one failed to copy. Windows gave an error message saying there was no room left. I then checked unRaid server and saw that the disk had a red ball. I tried to do a file system check in unmenu and got the message that no file system was detected.

I missed answering why I replaced the original drive; I just wanted more space and my case is full so I upgraded the drive to a larger size. The original was working fine before I upgraded it.

 

I did the Short Smart Test check and it said that there were no errors but that Drive Partitions - Not In Protected Array.

What does that mean?

that was just the tail end of your syslog.  It had tons of disk errors... looks like the disk stopped responding.

 

I'd power down, double-check all the connections to the disk are on securely.

That was just the end because the full file was over 200M. I am using Supermicro hard disk trays but I will check the connections. I would have thought that if drive Smart test completed that the drive could be accessed and there would not be a loose connection.

If the connection was intermittent, and you happened to run the smart command when it was good, you might get results that are misleading.  Trays can lose connection when they vibrate, or have a temperature change.  server activity can cause either.

It appears that my motherboard has died. I opened the case to check all the connections to the drive I am having the problem with and I also reseated the SAS RAID card. The system will now turn on but there is no video. I swapped the graphics card but still no video and now get continuous long beeps which the manual says is a power error. I changed the power supply but still get the beeps and no video. So I guess it is time to change the motherboard.

 

What motherboards are now being used for unRaid? I am now using a Gigabyte GA-EP450-UD3. Is there something new that will support the Supermicro AOC-SASLO-MV8 card?

Rick

Almost anything with a PCI-e x4 or better.

I need to read about unRAID 5 support I don't want to buy something now that may not be compatible with unRAIDd 5. I also want a board with 6Gbps SATA since the new WD drives I bought are 6Gbps drives. The Supermicro SAS RAID card I am using is only 3Gbps hopefully something new will come out with 6Gbps capability.

That sounds more like RAM to me. I'd pull all the RAM sticks, power up and see if the beep pattern changes. Then install 1 RAM stick at a time, and check beep patterns with each stick. If none of your combinations changes the beep pattern, THEN I'd give up on the motherboard.
