May 24, 201115 yr Hi there on my unraid server my disk 6 has red dot and says DISK_DSBL. I forgot to save the syslog and have since rebooted the server hoping that would be work but no luck. I do remember when I first seen the disk was disabled it said like 1500 write errors in the unraid menu. I have another replacement hdd if the drive is no good but want to make sure before I replace it. I have attached a smart report of the failed drive to look at. Any help is greatly appreciated. Thanks smart.txt
May 24, 201115 yr Author thanks but does anybody else have any opinions, and does my smart test look okay or what. also to replace the drive what are the correct steps to follow.
May 24, 201115 yr 5 Reallocated_Sector_Ct 0x0033 100 100 036 Pre-fail Always - 4 195 Hardware_ECC_Recovered 0x001a 037 020 000 Old_age Always - 63008507 197 Current_Pending_Sector 0x0012 100 100 000 Old_age Always - 3 198 Offline_Uncorrectable 0x0010 100 100 000 Old_age Offline - 3 None of those look very good - esp the #5 and #197, although not very high, better they at 0. Best bet, pull the drive and replace with a good one then try running preclear on this one and doing some testing. See of these numbers stay the same or go up... If they stay steady, you might be ok, but if they keep going up, definately bad. To replace drive, stop array, power down, replace drive with new one (same port) and then power up. the array shouldn't start automatically, as you have put in a different disk. Click to start the rebuild process. Make sure it is not asking you to format or anything like that though, as it shouldn't. Replace failed disk with one same size or larger, but not larger then the Parity disk. Shawn
May 24, 201115 yr The SMART results also indicate that the drive ran at 65 C at some point in the past. That is VERY hot, well outside the manufacturer's allotted range. It has hard to say if any permanent damage was done, but it is possible. Perhaps it would account for the 3 uncorrectable errors. Have you checked for loose cables or other possible hardware malfunctions? First, check for loose cables, that is the most common cause of a drive failure. If you don't find any, then I would suggest replacing disk6 with your replacement disk. Let unRAID rebuild the data onto the new disk. Once that is done, run a parity check, it should complete with no errors. After that you can take your time with the suspect disk and find out if it actually is failing or not.
May 24, 201115 yr Author okay I will try replacing the failed disk. My server has never moved since I built it and with my Antec 900 and 3 CSE-M35T-1B 5-in-3 its very tight in there and I have to basically dissemble the server to check for loose wires.
May 24, 201115 yr Author ok I replaced the failed disk with replacement and it's currently rebuilding. I wanted to get the failed disk replaced asap so the drive i put in wasn't pre-cleared or wiped clean. Unraid will take care of all that during the rebuild right. Thanks
May 24, 201115 yr Well, kind of. unRAID doesn't test the new drive at all, it just assumes that it is healthy. unRAID also doesn't clear or wipe the drive. Instead, it rebuilds the contents of the old drive bit for bit - included the file system. So if the old drive had a corrupted or damaged file system, the new rebuilt drive will as well. If you see this, don't panic, there are ways to correct it.
May 25, 201115 yr Author the replacement drive I put in was from a old computer I upgraded. So it has windows and windows files on it should i be worried or will unraid take care of it.

Thanks This happened to me recently. I took out the drive in question and loaded Windows on it. Performed well and had no issues. Really confused the heck out of me. I replaced the drive anyway but unfortunately by re-build didn't entirely work %100. I had lots of lost&Found files after a reiserfsck. I dunno what happened, and I didn't want to spend weeks sifting through lost&found files. If you install your hardware correctly you shouldn't have a loose cable or anything like that.

I dunno what happened, and I didn't want to spend weeks sifting through lost&found files. If you install your hardware correctly you shouldn't have a loose cable or anything like that. when any RAID system re-constructs a drive it does it at the bit level, not at the file level. If the disk that had failed had a corrupted file system, the re-constructed copy of it on a brand new replacement disk will have exactly the same corruption. It is therefore very possible to have reiserfsck put files into lost+found, even though the re-construction went perfectly if the file-system corruption occurred prior to the disk's failure. Joe L.
May 25, 201115 yr Author Ok so the replacement drive finished rebuilding and it works great. Just wondering I'm trying to preclear the failed drive to see if it fixes it but I keep getting an error. The error says a mandatory smart command failed I have attached a picture below. Does this mean the drive is officially no good or whats going on. Thanks

The error says a mandatory smart command failed I have attached a picture below. Does this mean the drive is officially no good or whats going on. Thanks Can you get a "smartctl" report on the drive? does it respond to an "hdparm" command? smartctl -a /dev/sdX hdparm -I /dev/sdX can you get it to show you the partitioning using fdisk? fdisk -l dev/sdX can you read it using "dd" dd if=dev/sdX count=1 | od -c If they all fail, the disk has probably seen its better days.

Joe L. Do you want me to enter all those in command prompt and Im currently pre clearing 2 other drives this wont effect them at all correct.
May 26, 201115 yr Author ok it fails the tests so the drive is no good. Can I pull the drive while the system is on or do I have to wait until its off. I currently have 2 pre-clears running so that will be in about 24 hours.

I currently have 2 pre-clears running so that will be in about 24 hours. to be safe, wait. if you do not yet have any drives assigned to the unRAID array, and the array is not started, you can probably unplug. On the other hand, are you sure it is the drive and not a loose cable (power or SATA), a bad cable (power or SATA), or a bad disk controller port? All could give the same symptoms.
May 26, 201115 yr Author yes im sure its not a lose cable as its in a different slot than before and it still has the same errors.
May 26, 201115 yr yes im sure its not a lose cable as its in a different slot than before and it still has the same errors. that would rule out a bad cable... Sorry your disk has died, but that is why we have unRAID arrays. Joe L.
