Hello,
I have an Astlinux installation using the latest 1.1.4-Asterisk-11.7.0 for
our Soekris net5501 hardware.
Astlinux is installed on Sandisk compact flash card.
In our situation, I cannot guarantee our users will not do a hard power-down
by unplugging the power cord.
Also, usage of a UPS is not an option for these installations.
But I wasn't too concerned, because I would expect there would be very few
configuration changes / writes to flash occurring in this system.
Once the system is setup, it might be year(s) before the configuration will
ever be changed.
But what I have noticed is that if I perform power cord unplug tests, I see
that in about 30% of the tests, fsck will fail, requiring manual
intervention to run a fsck fixup. In the other 70% of cases, fsck will
detect errors, but will be able to fix them up, and bootup occurs properly.
For the 30% fsck failure rate, the console message is as follows:
Configuring for unionfs...
Checking asturw filesystem
ASTURW: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
(i.e., without -a or -p options)
Fsck detected errors on /dev/sda2 (4)
execute fsck -t ext2 /dev/sda2 to attempt to repair errors manually.
Few questions / notes
- I am using high quality Sandisk Ultra / Ultra II compact flash
disks
- During these powerdown tests, Asterisk is quite idle. Only one
device is registered, no active calls on the go.
- Is this the expected hard fsck failure rate for ext2 filesystem ?
- Is there an option to run Astlinux with a ext3 filesystem for
/dev/sda2 ?
Thanks, Martin
