Solaris Volume Manager (SVM) : Understanding metadb Flags
The state database contains the configuration and status information of all volumes, hot spares and disk sets. To provide redundancy we create multiple copies of the state database called as state database replicas. Now in case of losing any state database replica SVM determines the valid state database replica by using majority consensus algorithm. According to the algorithm it is required to have atleast (half + 1) to be available at boot time to be able to consider any of them to be valid. … [Read more...] about Solaris Volume Manager (SVM) : Understanding metadb Flags
Solaris zones : How to set netmasks
Question : How to set certain netmask for a non global zone ? Answer : To define a certain netmask for a non global zone, use zonecfg command.

Solaris 11.2 : Adding new resources to a running zone online
Solaris 11.2 provides a supported way to add new resources to a running zone online. Prior to this version, a reboot of the non-global zone was required to make the changes effective. The post describes an example of adding a raw disk device online to a non-global zone. Example: 1. Check the Solaris OS version. # uname -a SunOS test 5.11 11.2 sun4v sparc SUNW,T5240 2. List the zones available on the system. In our example we will be adding disk resource to the zone - zone01 # zoneadm … [Read more...] about Solaris 11.2 : Adding new resources to a running zone online

How To Delete Files on a ZFS Filesystem that is 100% Full
When a ZFS file system has no space left then the deletion of files can fail with "disk quota exceeded". The post provides different ways to create free space to overcome the situation. 1. Truncating files If the files can not be removed directly, we can first truncate them and then delete them. # cat /dev/null > /file/to/delete # rm /file/to/delete Alternatives: there are other options to free up space in the zpool, e.g. 1. increase the quota if there is space in the zpool left 2. … [Read more...] about How To Delete Files on a ZFS Filesystem that is 100% Full
