so 4 days ago disk 2 gets red ball with errors. i do smart report and seems fine in my eyes.

i do the proper methods to rebuild the drive. it went at 5MB and took 3 days to complete

 

now that the rebuild is finished disk 7 is red ball.

i do the same methods as i did with disk 2.

 

im 8+ hours in going in at 5MB again but disk 2 is getting thousands and thousands of errors and still going

 

now im panicking. any help is much appreciated.

 

syslog, smart report for disk 2 & 7 are attached

Archive.zip

Disk2 is showing read errors in the syslog so you cannot successfully be rebuilding a different disk.

 

Also the SMAET report for disk2 shows it is very sick as it has lots of Pending sectors.  Any non-zero value will indicate a potential issue.  A small number sometimes rectifies itself but that drive Is showing 1445.

thanks for the reply. what should i do for now??

ill be picking up a new drive tomorrow after work.

I am not sure as with two disks having problems you cannot rebuild from parity.

 

The SMART report for disk 7 does not show any obvious problems with that drive.  It could have just been a temporary glitch (or perhaps a loose able) that caused it to get red-balled. 

 

I think any recovery of data from disk 2 and 7 is going to have to be attempted without them as part of the array.  I am hoping that the attempt to rebuild disk 7 with disk 2 playing up has not damaged its contents beyond repair/recovery.    However I would wait and see if anyone else chimes in with any good ideas.

I think disk2 and 7 will be a loss. Ideally you would have rebuilt disk2 on a new drive and this wouldn't be happening, or you would have rebuilt disk7 on a new drive, and your option now would be to attempt to use the original disk7 to rebuild disk2 again. I don't think that will be possible since you already started a rebuild on disk7 and it's contents are compromised.

 

Disk7 seems fine from the smart reports so it's likely there was never anything really wrong with it. I have had a couple red balls, but they ended up being a loose connection.

so disk 7 red ball half way through the rebuild after 2 days.

i took this time to replace disk 7 with a new 4tb disk

i just started the rebuild for the disk going at 10MB

 

hoping rebuild goes through so i can transfer files from disk 2 to disk 7

i will then either shrink the array or try the original disk 7 since you guys say it seems ok in smart reports

 

so far no data loss. im crossing fingers now

 

EDIT:

 

P.S. is it possible to move the content right now during rebuild or should i wait??

so rebuilding drive has come to a halt at 15% percent after 2 days and going kb slow now

at this point im looking into how to transfer files from failing disk to new disk

i will then start a new config without failing drive and start a new parity

what would be a great way to do that??

 

i have unassigned the drive for now so i can have it available to back up data

array wont let me add it as new disk since it wants a rebuild first

If you have a Windows computer, there are a couple of utilities that will read unRAID data disk.  Here are links to them:

Simplest way woould be to put the bad drive into a external USB adapter and plug it into your Windows Computer.  I have not had to use either one so I can not tell you if one is any better than the other.  However, YAReG does require MS's  .NET framework package to run and I seem to recall that that thing is a monstrous download. (There is a lot of other software which requires  .NET, so you might already have it on your computer.)

is there a way i can use the drive thats unassigned to backup within unraid using midnight commander??

i was thinking i can format the drive to unraid format and then back up and start new config to include the drive

 

i dont have a desktop pc i can do backups,etc

only have a macbook to do work and stuff but nothing heavy

Since no one else has jumped in to help, I can only point you in the right direction.  (I am no Linux expert and can not really give you a complete set of steps to do what you want.)  However, here are some links to the Linux command  -- mount ---  to make the disk 'visible' and how to use it with unRAID.

Since you are an Apple user, you might already to somewhat aware of this command as I understand that the Apple OS and Linux are both based on UNIX which contains the mount command to do this task.  (I also have the gut feeling that all of this is automated 'under the hood' in Apple's OS>)

 

EDIT: if you want more unRAID references, try searching for "mount" on the entire board.

thanks for the info

 

im currently doing this

 

[*]Preclear with preclear_disk.sh. (Already done.)

preclear_disk.sh /dev/sdX

[*]Partition with gdisk (included in UnRAID) accepting all defaults.

gdisk /dev/sdX

[*]Format with mkreiserfs accepting all defaults.

mkreiserfs /dev/sdX1

[*]Mount and share with Snap through GUI.

 

EDIT:

 

im getting read errors and not everything is copying

but if i mount the share on my macbook and copy over network it goes through

im wondering if i should just copy files over network even though itll be twice as slow

i cant be keeping an eye on the throughout copying if it needs me to skip a certain error file

UPDATE

 

i was able to recover 90% of disk 2

only lost 300GB of data which i recovered already thanks to my blazing internet speed

and not sure how but disk 7 was intact with all files and is running fine on the array

i guess the red ball for disk 7 was just a mistake or something

 

started a new config with the new drive

parity drive finished building just a while and array is valid

going to run a parity check just to make sure all is well

 

i also took this time to update to the latest stable version

and repair errors my flash was getting

 

just want to to say thanks for you guys input
