Yes i know about it, but it recognizes as:
ls -la /dev/da0*
crw-r----- 1 root operator 0, 77 Apr 28 17:23 /dev/da0
crw-r----- 1 root operator 0, 80 Apr 28 17:23 /dev/da0s1
crw-r----- 1 root operator 0, 93 Apr 28 17:23 /dev/da0s1c
and
#gpt show da0
start size index contents
0 1 MBR
1 62
63 3571210 1 MBR part 165
3571273 8589937079
but there was a 4TB slice with important data, i didn`t touch RAID - so
it`s should be there...
i didn`t remeber was it gpt or not :(
And yes hdd failed during reboot so RAID filesystem should be clean.
