Bacula mail changer script (aka poor man’s autoloader)
I enjoy Bacula for automated home backups on DLT and DDS tape drives. Being used at home there’s no – obviously – big-dollar-company-manager to ask for an autoloader; and when the time of a tape change comes bacula lacks a simple way to request a manual tape change and just hangs up. So I managed to build a fake autoloader shell script, which, using emails, would emulate a real autoloader. This script, which I baptised mail-changer, features:
- email support
- periodic email resend when tape change is needed
- tape detection and check (if you’re supposed to insert tape 4 and you enter 5, the script will kindly refuse the tape, unload it and send a warning email message asking for the right one)
Solaris 10 si3124 backport (workaround for bug #6566207)
Do you think you can get a fast cheap SATA mass storage at home with Solaris 10 and ZFS just plugging a cheap si3124 controller?
Not so easily: on Solaris 10 you will be afflicted by some boring bug known as bug #6566207 which gets your controller stuck for around a minute after some heavy I/O.
seq equivalent
On platforms without seq (MacOSX, Solaris), you can emulate it using dc as follows (note the upper bound and the lower bound):
echo '[1+pdupper bound>aq]salower bound 1-lax' | dc
For example:
alia:~ andrea$ echo '[1+pd5>aq]sa0 1-lax' | dc
0
1
2
3
4
5
alia:~ andrea$
