[SOLVED] 4.7 to 5.0 final upgrade - MBR: unaligned / file system type: unknown

[TDD]

Hello all!

 

Just did the upgrade from my very stable 4.7 to 5.0.

 

Followed instructions to the letter...backed up old install, reformatted, copied 5.0 over with relevant config files.

 

All boots well and all drives are in correct positions - green balls abound.

 

I check each drive before start the array and each says  that the MBR: is unaligned and the file system type is unknown.

 

All my drives are <2TB and were formatted long ago so I can accept the unaligned portion.

 

What is up with it not recognizing ReiserFS?

 

Am I safe to start the array?

 

Just for note...assuming I want all to be 4k aligned, I will have to copy all data off each drive, reformat that drive, and copy back per drive?

 

Thx for help in this!

Attach a syslog. There is no benefit to converting from unaligned to aligned. All new disks added to the array should be aligned but leave existing disks alone.

Syslog attached as zip...

It seems like the syslog is not complete. The last line:

Aug 31 22:56:00 FS atd[1410]: Exec failed for mail command: No such file or directory

 

Edit:  See dgaschk's sig and read over the "Check Disk Filesystems" link.......

I can't find the link now, but do a quick search for the file system : unknown message or whatever it is... it doesn't become "known" until the array is started. It's been covered, I ran across the same thing in my upgrade to 5.0 but remembered that it was expected.

I found the relevant post.  Makes sense and I agree that the wording could be tweaked.  Thx for heads up.  Going to proceed and get the array going!
