Hello,
since mdadm 4.3, trying to use numbers larger than 127 results in:
mdadm: Value "/dev/md3032" cannot be set as devname.
Reason: Not POSIX compatible. Value ignored.
Because in util.c :: is_devname_numbered() (commit 25aa73291):
if (val > 127)
return false;
The kernel seems to be fine with MINORMASK (2^20 - 1).
If so, instead of 127, the limit here should be 1048575?
I don't need a million arrays. But I do have more arrays than
average because I use partitions instead of one big array
for everything. And some flexibility in using distinct number
ranges per group of arrays makes /proc/mdstat easier to read.
Regards,
Andreas Klauer
