Problemas de espacio en disco al actualizar a Junos 9.6 en M7i

He tenido que actualizar recientemente un router de Juniper M7i, que tenía una versión de Junos 8.5, y 256 MB de memoria RAM. En primer lugar, es requisito para la versión 9.6 del sistema operativo que el router disponga de 512 MB de memoria en la controladora, y se recomiendan 768 MB. Por tanto, después de aumentarle la memoria a 768 MB, se podía actualizar el sistema. O quizá no.
Comando para actualizar por defecto:
request system software add jinstall-9.6R1.13-domestic-signed.tgz
Primer problema: la imagen no pasa la validación. Este es muy fácil de resolver:
request system software add jinstall-9.6R1.13-domestic-signed.tgz no-validate
Segundo problema: no hay espacio en disco. Mensaje que muestra:
tid@m7i> …ce jinstall-9.6R1.13-domestic-signed.tgz
Installing package ‘/mfs/var/home/tid/jinstall-9.6R1.13-domestic-signed.tgz’ …
tar: jinstall-9.6R1.13-domestic.tgz: Wrote only 0 of 10240 bytes
tar: certs.pem: Wrote only 0 of 10240 bytes
tar: Error exit delayed from previous errors
WARNING: Not enough space in /var/tmp to unpack jinstall-9.6R1.13-domestic-signed.tgz
WARNING: Use ‘request system storage cleanup’ and
WARNING: the ‘unlink’ option to improve the chances of success
Viendo el aspecto de las particiones podemos hacernos una idea de por dónde van los tiros:
Filesystem Size Used Avail Capacity Mounted on
/dev/ad1s1a 217M 98M 102M 49% /
devfs 1.0K 1.0K 0B 100% /dev
devfs 1.0K 1.0K 0B 100% /dev/
/dev/md0 23M 23M 0B 100% /packages/mnt/jbase
/dev/md1 80M 80M 0B 100% /packages/mnt/jkernel-8.5R4.3
/dev/md2 8.8M 8.8M 0B 100% /packages/mnt/jpfe-M7i-8.5R4.3
/dev/md3 3.5M 3.5M 0B 100% /packages/mnt/jdocs-8.5R4.3
/dev/md4 28M 28M 0B 100% /packages/mnt/jroute-8.5R4.3
/dev/md5 8.8M 8.8M 0B 100% /packages/mnt/jcrypto-8.5R4.3
/dev/md6 37M 37M 0B 100% /packages/mnt/jpfe-common-8.5R4.3
/dev/md7 504M 232M 231M 50% /tmp
/dev/md8 504M 277M 186M 60% /mfs
/dev/ad1s1e 24M 28K 22M 0% /config
procfs 4.0K 4.0K 0B 100% /proc
Sin embargo, en los mensajes del arranque se ve que el disco duro es bastante más grande que eso:
ad1: 28615MB <FUJITSU MHT2030AR 959C> at ata0-slave UDMA33
Algo falla ¿no? Efectivamente, el contenido de /etc/fstab revela particiones no montadas, en particular:
/dev/ad1s1f /var ufs rw,noauto 2 0
Montándola aparece una partición de 27 GB:
/dev/ad1s1f 27G 595M 24G 2% /mfs/var
Una vez montada la partición, la instalación se hace sin problemas, y después de reiniciar ya está disponible la versión de Junos 9.6.

Disk space issues when upgrading to Junos 9.6 in M7i
martes, noviembre 30th, 2010
Este texto está disponible en español: Problemas de disco al actualizar a Junos 9.6 en M7i.
I recently had to upgrade the operating system in a Juniper M7i router which was running Junos 8.5 and had 256 MB of RAM. First, a requisite to run Junos 9.6 is 512 MB of RAM in the routing controller, and 768 MB is recommended. I upgraded to 768 MB and I thought that was going to be it.
To perform a system upgrade, you have to issue this command:
request system software add jinstall-9.6R1.13-domestic-signed.tgz
The first problem that appears is that the
package does not validate. However, this is piece of cake:
request system software add jinstall-9.6R1.13-domestic-signed.tgz no-validate
Second problem: no disk space available. The message is shown below:
tid@m7i> …ce jinstall-9.6R1.13-domestic-signed.tgz
Installing package ‘/mfs/var/home/tid/jinstall-9.6R1.13-domestic-signed.tgz’ …
tar: jinstall-9.6R1.13-domestic.tgz: Wrote only 0 of 10240 bytes
tar: certs.pem: Wrote only 0 of 10240 bytes
tar: Error exit delayed from previous errors
WARNING: Not enough space in /var/tmp to unpack jinstall-9.6R1.13-domestic-signed.tgz
WARNING: Use ‘request system storage cleanup’ and
WARNING: the ‘unlink’ option to improve the chances of success
After entering the command shell and running «df», we may have an idea of where the problem is:
Filesystem Size Used Avail Capacity Mounted on
/dev/ad1s1a 217M 98M 102M 49% /
devfs 1.0K 1.0K 0B 100% /dev
devfs 1.0K 1.0K 0B 100% /dev/
/dev/md0 23M 23M 0B 100% /packages/mnt/jbase
/dev/md1 80M 80M 0B 100% /packages/mnt/jkernel-8.5R4.3
/dev/md2 8.8M 8.8M 0B 100% /packages/mnt/jpfe-M7i-8.5R4.3
/dev/md3 3.5M 3.5M 0B 100% /packages/mnt/jdocs-8.5R4.3
/dev/md4 28M 28M 0B 100% /packages/mnt/jroute-8.5R4.3
/dev/md5 8.8M 8.8M 0B 100% /packages/mnt/jcrypto-8.5R4.3
/dev/md6 37M 37M 0B 100% /packages/mnt/jpfe-common-8.5R4.3
/dev/md7 504M 232M 231M 50% /tmp
/dev/md8 504M 277M 186M 60% /mfs
/dev/ad1s1e 24M 28K 22M 0% /config
procfs 4.0K 4.0K 0B 100% /proc
That is weird, isn’t it? The boot messages show that the hard disk is quite bigger than that:
ad1: 28615MB <FUJITSU MHT2030AR 959C> at ata0-slave UDMA33
So there is something wrong, right? Right. «cat /etc/fstab» reveals umounted partitions, for instance:
/dev/ad1s1f /var ufs rw,noauto 2 0
After mounting /dev/ad1s1f, a 27 GB partition appears:
/dev/ad1s1f 27G 595M 24G 2% /mfs/var
There it is, we have plenty of space to perform the upgrade. This was a big headache, after all. I hope that anyone having the same problems may find this helpful.
