EXT4 Filesystem Issues

#1 Post by theone » 15 Sep 2016, 05:21

Hello Folks, I had a problem with my RAID5 Controller, after change for the SAME Model and Trademark, I tried to mount it on my Filesystem but ask to runs FSCK.EXT4 utility, I tried to run but my RAID is 16TB (5 disks 4TB SAS), the system taken around 4 days and never finish the process, no status bar or percentual to let me know about the process status or something else to mensure the time to go, OK, I Try to run TESTDISK (I'm sure that I've an EXT4 Partition) but the system shows me that:

am I doing something Wrong ?! Steps: New Log => /dev/md1 => Intel => Quick Search

If I understand correctly, your computer is using a software Raid (aka fakeraid).
Your Raid device is /dev/md1. The capacity seems correct (16 TB).
TestDisk has listed "Partition Type: None" when you have select this device (It would have been easier if you had copy/paste the testdisk.log file content...)
What is the exact fsck message ?
Did you stop the fsck ?
"fsck.ext4 -vty /dev/md1" should display some information about its progress.
Using TestDisk, what is the result of TestDisk, Advanced, List ?

Yes, I stop the process, cuz it's took more than 4 days, NOW finally I have this screen Below: (I'm able to navigate for all of my Folders and I can see the content inside), I just don't know how can I fix it or mount it again, If you can give me any support or Clue, I'll appreciate so much, Thanks in advance.

fat12? that's for floppy disks. are the drives formatted properly?

I know sometimes things can hang on boot because they look for floppy drives that aren't there.

No ! This is was always EXT4, like I've told you before, the filesystem structure or partition has problem, I can recovery the folders with Testdisk, But I want to know if I can fix the whole disck partition or Filesystem sctructure using testdisk, It's 16TB a huge large files...

- Yes, I'm using software RAID (mdadm) and my RAID array have 16TB It's a RAID 5 with 5x 4tb SAS.
- Trhough Testdisk I can navigate on directories and Files, Now I'm trying to use the method of Copy and Paste (Past in another Disk, But I will try to manually paste in 8 disks of 8TB, cuz the amount is very Huge).
- YES ! I've stopped FSCK.EXT4 -v -y because it's took 4 days without any progress, I just have a lot messa of CLAIM BLOCKS but the process seems to be increbible slowly.

My last testdisk.log:
