OK, if not Linux boxes, then what should one use? Is R-Studio capable of working on this type of lvm2 volume some other way?

Thanks,

A similar issue happens with Acer Altos NASes

Have you solved the issue?

Alt and all,

I have successfully used R-Studio for Linux in the past to recover Synology RAID5 volumes. The new Synology arrangement under DSM 5.0 uses LVM2 (virtual volumes). I lost some folders and many files when connecting the RAID drives to Ubuntu (do not know the reason at this time) and was ...

Thanks.

There is now very little doubt that we got the correct parameters for the RAID. We found several PDF files that were made out of PowerPoint presentations. Some of them were over 200 MB and all the slides and pictures in a select few displayed perfectly. Therefore, the damage to the drive ...

Every time we ran a full scan the "extra files" feature was on.

Do you think a 622K file should have been big enough to determine if disk order/blocksize/offset was correct? With 4 disks, 64K block I think a stripe would be either 64K or 256K, correct? (I read about this, but right now forgot how ...

OK, so we are about ready to through in the towel...

As far as we can tell, the damaged RAID5 volume has the following attributes:

4 drives, using Partition 3 on the 4 drives (there is a hot spare, but that shouldn't matter).
Linux software raid inside a Synology 1010+.
Total volume size aprox ...

Will R-Studio for Linux be similarly updated soon?

Thanks,

I mean that the Synology may have reformatted the RAID5 (data) partition. I can find 3 volumes in there with R-Studio and the one that was lost was done with a previous version of the firmware, so it has a different "number" on it (please see the recovered information on the enclosed .png files ...

OK, so I found some old logs on the first partitions of the drives (which are not RAID).

Looking at message logs from last year, I found this section which seems to show how the RAID was configured. It seems to show the disk order (sda3, sdb3, etc...) at the bottom, but I don't see any clues as to ...

Hi.

Have a Synology Diskstation 1010+. Data RAID volume got corrupted and may have been reformatted. Raid5+hot spare, 5x2TB disks. Using R-Studio for Linux (Ubuntu).

Read a lot about RAID recovery here and elsewhere, but only found instructions on how to manually figure out disk order/offset ...
