Thanks, good to know.
Actually I wasn't asking if it was enough, I was asking if it was too much lol. I've heard that every 100GB of L2ARC steals ~2GB of RAM from ARC. So I just wanted to ask if a 400GB to 128GB L2ARC:ARC ratio was good.
That implies you'd lose 8GB RAM to L2ARC management.I've heard that every 100GB of L2ARC steals ~2GB of RAM from ARC. So I just wanted to ask if a 400GB to 128GB L2ARC:ARC ratio was good.

Not possible, you cannot replace a 512B disk in a vdev with ashift=9 with a 4k disk and current ZFS.
You can try to buy a 512B disk or do a backup and recreate a pool with ashift 12.
Ashift is a property of a vdev that is set during creating a pool or adding a vdev.
so I will destroy the vdev and re-create it with my 4k+512b disks with ashift=12.
If OI boots, OmniOS should boot as well as they share the same bootmechanism and both are Illumos distributions.
If you want to stay with OI 151a, your problem is that there have been no security updates in the meantime like the critical OpenSSL fixes. If you want to use an old OI with a newer napp-it, check https://www.napp-it.org/downloads/openindiana_en.html about howto achieve this.
Other options:
OI Hipster (no stable but newer)
OmniOS (what is the problem, have you tried USB or CD boot optionally with a reloaded iso)
#!/bin/sh
printf '%s\n' "My Message A" | tee --append myscript.log
printf '%s\n' "My Message B"
printf '%s\n' "My Message C"
printf '%s\n' "ok"
@Gea: Would it be possible to make the condition be dependent on the exit status for the script? In that case one would write the exit code in the condition. Completed by an input text field with the message of exit code for the nappit log.
If you do not enter anything in keep or hold,
you will see two snaps per filesystem.
if you enter for ex 00 in keep, any snap that ends with 00
ex ..100, ..200 are kept unless you destroy manually
If you enter for ex 14 in hold, you will hold all snaps
(for all filesystems) for 2 weeks. Older replication snaps are
deleted.
Thanks Gea. Unfortunately the snapshots are piling up on my system and I've left the field blank. Do you think this is because I'm running on OI?
I do not test the newer releases with OI.
If you use an older napp-it release, you may try the current release.
#!/bin/sh
pathlog="./test.log"
> "$pathlog"
printf '%s\n' "$(date +%Y-%m-%dT%H:%M:%S%Z)" | tee --append "$pathlog" # works in console and "other job"
printf '%s\n' "$(date -u +%s)" | tee --append "$pathlog" # works in console and "other job"
printf '%s\n' "$(date --utc +%s)" | tee --append "$pathlog" # works in console only
printf '%s\n' "$(date -d @1452193692)" | tee --append "$pathlog" # works in console only
printf '%s\n' "$(date --date='@1452193692')" | tee --append "$pathlog" # works in console only
printf '%s\n' "$(date --version)" | tee --append "$pathlog" # works in console only
You can start a script from console via Perl like
perl -e ' system("sh /path/yourscript.sh") ;'
my $r=`$action 2>&1`;
perl -e ' system("sh /path/yourscript.sh") ;'
perl -e ' `sh /path/yourscript.sh` ;'
my $r=`$action 2>&1`;
perl -e ' system("sh /path/yourscript.sh") ;'
perl -e ' `sh /path/yourscript.sh` ;'
If you want to create a file from a rpool snap for recovery purpose you can create one or two
shellscripts with the three needed commands and execute them with an "other job" to have
always the last or the two last states of rpool on your datapool.
But this is a very complicated way to do a recovery.
I have done some tests with OpenIndiana Hipster
(20151003 from http://dlc.openindiana.org/isos/hipster/) and found the following
- gcc not installed
pkg install gcc-48
- Perl Module Carp not installed, you must install from CPAN or
edit /var/web-gui/data/wwwroot/cgi-bin/admin.pl and comment out
use CGI::Carp at line 4
- Perl Module Expect with Tty.pm not working
(ex menu user). You must recompile/ install Expect
I will add these modules to current 0.9f6 and the bugfix edition 0.9f7
so OpenIndiana Hipster should run again - maybe tomorrow
update:
OI Hipster (October) is supported from napp-it 0.9f6 (Dec 22, 2015)
