Package: hdparm
Version: 9.43-1.1
Severity: normal
Dear Maintainer,
After attempting to persist some hdparm setttings using the hdparm.conf file I
noticed
that (none of) the settings were being applied at boot.
each boot resulted in the following in /var/log/sysconfig:
Jan 17 19:39:21 debian hdparm[206]: Setting parameters of disc:
/dev/sda failed!
Jan 17 19:39:21 debian hdparm[206]: /dev/sdb failed!
Jan 17 19:39:21 debian hdparm[206]: /dev/sdc failed!
Jan 17 19:39:21 debian hdparm[206]: /dev/sdd failed!
The alterations to my hdparm.conf file were:
mult_sect_io = 16
and a block at the end of the file:
/dev/sda {
write_cache = on
}
/dev/sdb {
write_cache = on
}
/dev/sdc {
write_cache = on
}
/dev/sdd {
write_cache = on
}
I *can* set these options manually:
# hdparm -m16 --yes-i-know-what-i-am-doing /dev/sda
/dev/sda:
setting multcount to 16
multcount = 16 (on)
# hdparm -W1 /dev/sda
/dev/sda:
setting drive write-caching to 1 (on)
write-caching = 1 (on)
If I remove the "mult_sect_io = 16" option from the hdparm.conf file,
(and leave the block dealing with the write_cache) then the settings are
applied correctly when the machine boots and I get the expected confirmation
of this in /var/log/sysconfig, e.g.:
Jan 17 20:30:20 debian hdparm[207]: Setting parameters of disc:
/dev/sda.
Jan 17 20:30:20 debian hdparm[207]: /dev/sdb.
Jan 17 20:30:20 debian hdparm[207]: /dev/sdc.
Jan 17 20:30:20 debian hdparm[207]: /dev/sdd.
I *suspect* that the problem relates to the fact that you can't use the -m
option
on the command line without the --yes-i-know-what-i-am-doing switch, (this is
just a guess but I can't see any sign of this switch in the init script, there
is also no mention of needing this switch in the man page.)
Regards,
Craig
