DESCRIPTION

SmodR modifies information about SRB resourceName

Note that the command can used only by SRB Administrators.

OPTIONS

-a

add a physical resource to a logical resource. If logical resource is not there then it is created

-l

remove a physical resource from a logical resource

-i

insert or modify access to a resouce for a given user

-d

delete access to a resouce for a given user

-o

change resource ownership to a given user

-x

modify maximum latency of resource (given in milliseconds)

-n

modify minimum latency of resource (given in milliseconds)

-b

modify bandwidth to/from a resource (given in MegaBitsPerSec)

-c

modify maximum allowed concurrency of resource (numeric)

-s

modify striping of resource (numeric)

-h

modify number of hierarchies in the resource (numeric)

-g

modify maximum capacity of resource (given in GigaBytes)

-r

rename a resource (logical or physical)

-z

modify description of resource

-u

modify current usage for user to currDataSize (numeric in GigaBytes) at the given timeStamp; if timeStamp is -1 then the times- tamp is internally generated. this information is kept historic and is not over written.

-q

set current quota and usage for user@domain to quota and currentUsage (both numeric in GigaBytes); if quota is -1 then the quota is not changed this information is unique per user-resource pair and gets overwritten when changed. If max_quota is -1 then the quota is not changed. If the user@domain = ALL then the usage is computed (from internal metadata in MCAT) for all user for that resource. The quota value is used if given else if -1 is given then DEFAULT_RESOURCE_USAGE_QUOTA from the runsrb environment variable is used unless the quota is set already for a user and resource pair. If the user@domain = ALL and the resourceName = ALL then the usage is computed for all users and all resources. The quota value is used if given else if -1 is given then DEFAULT_RESOURCE_USAGE_QUOTA from the runsrb environment variable is used unless the quota is set already for a user and resource pair.

-Q

enforce the quota by reducing access to null for all users in resources where their quota was exceeded. Apply this after executing "SmodR -q -1 -1 ALL ALL".

-D

disable write access to the physical resource (free_space = -4).

-E

enable write access to the physical resource (free_space = -1).

-L

modify the location of a resource
