RAID member drive partitions not set to FD00
by mfoley from LinuxQuestions.org on (#6N4TK)
I have a RAID array that used to be a 4-drive RAID-6 but I converted it to a 3-drive RAID-5 just using mdadm and never actually taking the machine down. This was at least a couple of years ago.
Recently, I was looking at the RAID-5 drive members and noticed that the partions are type 0700 Primary, not FD00 Linux raid autodetect:
Code:# gdisk -l /dev/sda
GPT fdisk (gdisk) version 1.0.8
Partition table scan:
MBR: protective
BSD: not present
APM: not present
GPT: present
Found valid GPT with protective MBR; using GPT.
Disk /dev/sda: 7814037168 sectors, 3.6 TiB
Model: WDC WD40EFRX-68W
Number Start (sector) End (sector) Size Code Name
1 2048 7812499455 3.6 TiB 0700 primaryNow, I could swear that when I initially created this array as a RAID-6 I specified the "Linux raid autodetect" partition type. I don't know whether I'm recalling incorrectly or the process of converting the RAID-6 to RAID-5 changed the partition type to 0700 primary.
However it happened, is this a bad thing that the partitions are set to 0700 instead of FD00 and should I change the partition types to FD00? It's been running for a couple of years (or more) like this so it doesn't appear to be hurting anything.
