I've been trying to cover data from a disk that appeared to had been corrupted after a power outage. The original setup was lvm on md raid 1 which appears to be what is complicating the issue. Apart from /boot, everything was on LVM partitions so I don't have any backup lvm information.
Following various guides online, I've recreated duplicated the raid partition with dd onto a new disk, recreated the raid 1 array with missing device, but the pv cannot be found.
I've tried to find the lvm uuid using this guide https://www.howtoforge.com/recover_data_from_raid_lvm_partitions but despite dumping twice the data to file, there are no plain text configuration information. The drives are not encrypted so that isn't likely to be the problem.
I also used testdisk to try to recover the partitions but it says they cannot be recovered. During analysis, it was able to detect the lvm partitions, extracted output: Linux LVM 1069 146 38 60799 228 29 959567608 Linux 1069 179 7 57740 22 10 910409728 Linux 790 66 45 59780 237 33 947685112 Linux 1069 179 7 57740 22 10 910409728 Linux 29283 103 5 85953 201 8 910409728 Linux 29292 181 10 85963 24 13 910409728
The numbers are start CHS, end CHS and size in sectors. There seems to be way more possible partitions than there should be, possibly results of previous LV resizing.
With only such data left, is there any possible way to reconstruct the PV/VG/LV without the uuid and recover data?
