Array Disk Name Changed to /dev/m127

ajmeireles
Hello! I doesn't know if is the correct section to this question, please sorry me if I'm wrong. I want know if here on community have someone that have the same problem(while I waiting the response of cPanel support). Yesterday I had some problems on the server and it forced me to reboot some times the server, all reboot was fine and server return to use without any issues, but I checked that after reboot was completed the array disk name of raid1(user basefiles) has changed from /dev/md3 to /dev/md127, the array raid1 continue working without any issues, but I need understand what's happened. I found some information in other forums, but I saw nothing that could be a serious problem so I decided to open this topic to find out if anyone with experience in WHM has had the same problem. Has anyone experienced anything similar using WHM? Is there any way to change the name and fix it so that it no longer occurs? Is moving the array having files written to it a risk?

    Hello, I believe this is addressed more accurately in the following: 606481 " raid device created as /dev/md0 is renamed to /dev/md127 after reboot

    What worked for me was to simply specify the array using /etc/mdadm.conf

    I have the same problem and the resources found on the web did not work for me.

    @triatlas - cPanel itself doesn't control the partitions on the machine as that is entirely up the operating system. I don't see that the bug posted earlier has been resolved, so it likely still affects some users.

    @cPRex Thanks for your comment. So am I right that at the time being there is no possibility to add a second RAID 1 on centos 7?

    That would be a good question for your host to answer about your specific hardware and configuration, as cPanel doesn't manage any of that. All disk and partitioning is up to the OS and hardware.
