Pinned topic quota on remote filesystems

‏2014-05-23T19:43:05Z |

title says it all - is it possible to add some of the quota related mount options

using mmremotefs update ... -o and thus enable things like mmrequota on

remote filesystems?

 

thanks.

    Quota administration, like all other GPFS admin tasks, can only be performed from home cluster nodes.  Quota tracking and enforcement will work the same way on remote nodes as on local nodes, provided the sysadmin on remote nodes configured the mounts correctly.

    thanks, yuri! what makes mmrepquota so special in this case (it does not work on remote filesystems)?

    This isn't something unique to mmrepquota, it's the basic GPFS administration model.  File system administration has to occur on the home cluster.  Remote clusters can mount file systems from other clusters, but not perform administration tasks.

    mmrepquota has quota information about other users so is root priviledged and should remain just in the base cluster.

    mmlsquota is allowed across cluster because the information is just for a particular user. It has the -C clustername option to do this.
