Where does mdadm create its own conf file?
When the program was installed it created its own mdadm.conf file as /etc/mdadm/mdadm.conf but all I see in it are comment lines. A few examples I have read show creating the file in the mdadm directory but most show creating it in etc not the mdadm sub-directory.
What should the value of mdadm be in superblock?
The value should be a 128 bit uuid in hexadecimal, with punctuation interspersed if desired. This must match the uuid stored in the superblock. The value should be a simple textual name as was given to mdadm when the array was created.
What causes mdadm to look for assembled container arrays?
The word containers will cause mdadm to look for assembled CONTAINER arrays and included them as a source for assembling further arrays. The word partitions will cause mdadm to read /proc/partitions and include all devices and partitions found therein. mdadm does not use the names from /proc/partitions but only the major and minor device numbers.
What does the program line in mdadm mean?
The program line gives the name of a program to be run when mdadm –monitor detects potentially interesting events on any of the arrays that it is monitoring. This program gets run with two or three arguments, they being the Event, the md device, and possibly the related component device.
Where do I find examine option in mdadm?
Use mdadm –examine for more detail. You can get more detailed information by using the -E or –examine options: This information is similar to that displayed when using the -D option with the array device, but focused on the component device’s relationship to the array.
How to start an array in mdadm on Windows?
Starting an Array. To start all arrays defined in the configuration files or /proc/mdstat, type: sudo mdadm –assemble –scan To start a specific array, you can pass it in as an argument to mdadm –assemble: sudo mdadm –assemble /dev/ md0; This works if the array is defined in the configuration file.
Why does mdadm-examine not work in RHEL?
But that doesn’t seem to work for me – in particular the array is presented as /dev/md/ :pool, where the mdadm –examine outputs /dev/md/pool. Am I doing something wrong? Is there something odd about my version of mdadm?
