My ThinkStation runs CentOS 7 which I installed on a BIOS RAID 0 setup with two identical 256 Gb SSDs after removing Windows. It runs fine but I just discovered in gparted something that does not seem right: - Launching gparted it complains "invalid argument during seek for red on /dev/md126" and when I click on Ignore I get another error "The backup GPT table is corrupt, but the primary appears OK, so that will be used." I then click on OK whereupon I again see the second error message. I then see "Not all of the space available to /dev/sdb appears to be used, you...

Hi all, we got a new test system here and I just also tested btrfs raid6 on that. Write performance is slightly lower than hw-raid (LSI megasas) and md-raid6, but it probably would be much better than any of these two, if it wouldn''t read all the during the writes. Is this a known issue? This is with linux-3.9.2. Thanks, Bernd -- To unsubscribe from this list: send the line

Because /dev/md126 clearly is part > of a software RAID. IIRC the old dmraid support for motherboard RAID has been phased out, but mdraid has grown support for Intel (and maybe some other?) common motherboard RAID. So, /dev/md<foo> doesn't inherently mean "Linux software RAID" for a while now...

...referenced in fstab as, e.g. /dev/md0, aren't handled correctly by inspection. This looks a bit more complicated. In my test guest, the guestfs appliance automatically creates the 2 md devices as: * /dev/md/localhost:localdomain:0 * /dev/md/localhost:localdomain:1 These are symlinks to ../md126 and ../md127 respectively. I haven't yet worked out why they aren't created as md0 and md1 as in the guest. I think here we need to either work out how to make the appliance detect and use their names (if this is even possible), or to map the names appropriately using information from /...

Hello! On my server PC i have Centos 7 installed. CentOS Linux release 7.6.1810. There are four arrays RAID1 (software RAID) md124 - /boot/efi md125 - /boot md126 - /bd md127 - / I have configured booting from both drives, everything works fine if both drives are connected. But if I disable any drive from which RAID1 is built the system crashes, there is a partial boot and as a result the Entering emergency mode. By all rules RAID1 in case of similar failur...

...ess would stop short very early in the process. Now, I have backups of the important stuff of course, so no real catastrophe. But it would be nice if I could get back the data from my disk directly. I booted a rescue disk (Slax 9.6.4) and I can see my disks as well as raid arrays /dev/md125, /dev/md126 and /dev/md127. Oh, my partitioning scheme is manual and quite simple. Everything is RAID 1, I have a /boot array on /dev/sda1 + /dev/sdb1, swap on /dev/sda2 + /dev/sdb2 and / on /dev/sda3 + /dev/sdb3. I tried to mount /dev/sda3 directly from the rescue disk: # mount /dev/sda3 /mnt But I only...
