Introduction
- In all this document we will refer to the Space Reservation administration. Space Reservation is also known as Token.
Connect to the SrmSpaceManager Admin Console
- Two options:
- a) Using pCells, locate the SrmSpaceManager cell (under the srm-${hostname}Domain).
- b) Logging to dccore.pic.es like this: ssh -2 -x -o StrictHostKeyChecking=no -l admin -c blowfish -p 22224 dccore.pic.es
Managing the Space Reservation
Create a Space Reservation
- The command to add a space reservation is reserve space.
reserve space -al=online|nearline [-desc=string] -lg=name [-lifetime=seconds] [-owner=user|fqan] -rp=replica|custodial size
- If no lifetime is given, the reservation will never expire
- size is defined in bytes, but accepts an optional by suffix using either SI or IEEE 1541 prefixes.
- As an example, to add a 4TB disk-only token named ATLASTESTDISK in the link group linkgroup-atlas
reserve space -al=online -rp=replica -lg=linkgroup-atlas -owner=/atlas -desc=ATLASTESTDISK 4000000000000
Update a Space Reservation
update space [-desc=string] [-eternal] [-lifetime=long] [-owner=user|fqan] [-size=bytes] spacetoken
- size is defined in bytes, but accepts an optional by suffix using either SI or IEEE 1541 prefixes.
- As an example, to update the space reservation ATLASTESTDISK to 5TB
update space -desc=ATLASTESTDISK -size=5000000000000 <token_id>
- Is possible that you have several tokens with the very same description. Only one of them should be in state RESERVED, all others should be RELEASED. In case of doubt try to figure out which is the token ID of the token being used (ie: look at the monitoring at dcmon.pic.es).
Release Reservation
release space token
List Space Reservations
ls spaces [-a] [-al=online|nearline] [-e] [-h] [-l] [-lg=string] [-limit=rows] [-owner=user|fqan] [-rp=replica|custodial] [-state=reserved|released|expired] ... [token|pattern]
List Link Groups
ls link groups [-a] [-al=online|nearline] [-h] [-l] [-rp=output|replica|custodial] [name]
List File Reservations
ls files [-a] [-h] [-limit=rows] [-owner=user|fqan] [-p] [-state=transferring|stored|flushed] ... [-token=long] [pnfsid|path]
