commands
- Create filesystem: sammkfs <fs>
- fs info: samfsinfo <fs>
- sam-fsd Check mcf, defaults.conf, diskvols.conf file for correctness
- samd config Initialize environment and apply changes to mcf, etc.
equipment types (mcf)
- ms = fs with archiving, data + metadata on same device. only accepts md types
- ma = fs with archiving, data and metadata on separate devices,
- md = striped or RR using DAU for storing data
- mm = metadata device. can specify multiple. stored RR if there are multiple by default
- mr = striped or RR device for storing data, uses SAU
- gxxx = stripe groups, 0..127

Disk VSN recycling can only be done by archive set. See sam-recycler(1M). Where vicepa.1 is defined by vicepa.1 dk -pool test_pool,
params vicepa.1 -archmax 21474836480 vicepa.1 -unarchage access vicepa.1 -sort path vicepa.1 -recycle_mingain 10 vicepa.1 -recycle_minobs 10
sam-recycler should be run by cron. You can specify family_set or archive_set as options to recycle by family/archive set at different intervals.
Maximum tar file size:
archmax = dk 10737418240
VSN Pools:
vsnpools test_pool dk MD1K-BIG-LZJB-SAMFS1 endvsnpools
Archive set to VSN assignment:
vsns allsets.1 dk -pool test_pool vicepa.1 dk -pool test_pool no_release_special.1 dk -pool test_pool no_release_dotvol.1 dk -pool test_pool no_release_direntry.1 dk -pool test_pool no_release_lock.1 dk -pool test_pool no_release_dotfiles.1 dk -pool test_pool endvsns
/etc/opt/SUNWsamfs/releaser.cmd
Specifies directives to sam-releaser, such as how to determine what files to release, age, various weighting metrics. See releaser.cmd(4).
logfile = /var/log/samfs/releaser.log rearch_no_release min_residence_age = 1800
To apply per-fs, set fs = <filesystem>. fs-specific directives override global directives.
/etc/opt/SUNWsamfs/diskvols.conf
Assignes VSNs to disk volumes.
