That severity was exaggerated. Works fine over here locally, with an
LIO target setup.
It doesn't work here...

Dear Maintainer,
* What led up to the situation?
New Debian 10 Buster fresh installation with HBA cards and disks
arrays
multi-attached ((2 HBA cards, 2 arrays of 12 disks, 4 links)
Disks are all listed correctly in /dev/ or /dev/disk/by-*/
* What exactly did you do (or not do) that was effective (or
ineffective)?
install multipath-tools (and depencies)
write wanted aliases in /etc/multipath.conf (see attached file)
* What was the outcome of this action?
tryied 'usual' commands, to apply/refresh configuration:
multipath -F
multipath -r
multipath or systemctl restart multipathd.service
It doesn't work as expected: 'multipath -v2 -ll' should have shown a
populated devices state map: it's empty.
/dev/mapper/ is empty. /dev/dm-* are not present.
/etc/multipath/wwids is not updated/replaced.
Do you not have /etc/multipath/bindings file generated in your case ?
No. I've attached a strace (str.multipath.txt) to the original report.
Files in /etc/multipath/ are not created (bindings) nor updated (wwids).
A lot has changed lately in how multipath-tools works and you may have
to fiddle around with settings.
Any doc pointer? From Buster manpages, my configuration and my usage are
correct. Have I missed a new option?
But I have it running fine here on my 2 local setups: sanboot and usual
one.
* What outcome did you expect instead?
Aliases in /dev/mapper/ to use with zfs-dkms.
Note:
The exact same machine works just fine on Debian 9 Stretch (with zfs-
dkms).
A upgrade to Buster, with untouched /etc/multipath.conf works just
fine also.
You mean the same old configuration file from Stretch works fine on
Buster ?
Yes (same old file from stretch) and no (work not so fine). It work as
expected (ie: alias are created in /dev/mapper) at first (as the
/etc/multipath/wwids exist, with actual disk ids). But, if any change is
made in /etc/multipath.conf, it's not applied on 'wwids' or 'bindings'
files.
