Units for "snapshot show -fields size"

SMLocke — Wed, 04 Jun 2025 22:03:57 GMT

I've got a fair number of volumes with daily and weekly snapshots (i.e., snapshots whose names start with daily.2016-02* or weekly.2016-02*), and my management is getting curious about how much space the snapshots are taking up in a given SVM. It feels like a command as simple as snapshot show -vserver foobar -fields size -snapshot weekly.* will do the trick, and it mostly is? Except that snapshots less than 1GB are shown in megabytes, and I'd love it a great deal if the CLI would show me all the numbers in GB, even if it's less than 1 (i.e., 0.43GB or what have you). Is that a thing I can do? Or is there some other kind of voodoo I'd need to do with OCUM (5.2, if that's relevant)?

Thanks!

Use the "set" command. Here are the options for units:

    [-units {auto|raw|B|KB|MB|GB|TB|PB}] - Data Units
         Use this parameter to specify the default units used when reporting data sizes. Possible values are:

         o   auto - Auto-scale data size for human-readable output

         o   raw - Bytes without unit designation

         o   B - Bytes

         o   KB - Kilobytes

         o   MB - Megabytes

         o   GB - Gigabytes

         o   TB - Terabytes

         o   PB - Petabytes

         The default setting is auto.

For example, to always display in MB you would use "set -units MB" from the clustershell.

Hope that helps.

This did the trick!

Caveat: setting units to GB will show all values less than 1GB as 0GB, not as a decimal value between 0 and 1 GB. Therefore setting units to MB (in my use case) makes more sense.

Thanks!
