Solaris – Add swap to ZFS disk
I installed Solaris 10 05/09 on a machine and I used whatever the default swap space setting when I built the box. Now I need to increase the swap space and I can’t add a swap file, like was possible under UFS.
If your swap device is in use, then you might not be able to delete it. Check to see if the swap area is in use. For example:
$ swap -l
swapfile dev swaplo blocks free
/dev/zvol/dsk/rpool/swap 182,2 8 4194296 4194296
In the above output, blocks == free, so the swap device is not actually being used.
If the swap area is not is use, remove the swap area. For example:
$ swap -d /dev/zvol/dsk/rpool/swap
Confirm that the swap area is removed.
$ swap -l
No swap devices configured
Resize the swap volume. For example:
$ zfs set volsize=1G rpool/swap
Activate the swap area.
$ swap -a /dev/zvol/dsk/rpool/swap
$ swap -l
swapfile dev swaplo blocks free
/dev/zvol/dsk/rpool/swap 182,2 8 2097144 2097144

Solaris – Zones, In the Beginning
Uso Solaris da quasi un anno ma non mi sono mai cimentato nell’uso delle famose Zones riassumendo i poche parole giusto per capire di cosa si parla dico: “operating system level virtualization”
bash-3.00# zonecfg -z Z01
Z01: No such zone configured
Use ‘create’ to begin configuring a new zone.
zonecfg:Z01> create -b
zonecfg:Z01> set zonepath=/zones/Z01
zonecfg:Z01> exit
bash-3.00# zoneadm -z Z01 install
Preparing to install zone <Z01>.

Sorry, I don’t know anything about your “xterm-color” terminal.
Oggi durante una serie di comandi con un senso ben preciso Solaris mi ha parlato in questo modo:
Sorry, I don’t know anything about your “xterm-color” terminal.
La perplessità generale mi ha fatto lanciare questo comando:
bash-3.00# export TERM=vt100
Ma molto probabilmente sarebbe stato meglio un terminale “ansi”

Solaris – Patch It
Un piccolo memo sul sistema di gestione delle patch in Solaris, patch ID 121118 (SPARC version) o 121119 (x86 version)
Questi sono i comandi principali:
Analyze: -/usr/sadm/bin/smpatch analyze
Download: -/usr/sadm/bin/smpatch download
Add Patch: -/usr/sadm/bin/smpatch add
Bisogna registrare il sistema con questo comando:
# /usr/sbin/sconadm register -a -r /tmp/registrationprofile.properties
Il file /tmp/registrationprofile.properties deve essere una cosa simile a questo:
userName=newuser
password=newpassword
hostName=
subscriptionKey=
portalEnabled=false
proxyHostName=
proxyPort=
proxyUserName=
proxyPassword=

Da qualche mese a questa parte ho avuto la pazza idea di usare solaris, credo che non ci sia migliore cosa che provarlo in produzione, quindi ho spolverato una Ultra 10 presa tempo fa e mai seriamente utilizzata, tolto la SunPCI e installato Solaris 10.
