Using touch to modifiy the date stamps on files in the dCachescratch area is not enough to update theuse date. I think you have to open the files but we can test this,though a test will take a while (1 month).
is more dCache monitoring then you can shake a stick at.
dCache ‘mv’ gotcha – if you ’mv’ a file from one pool type to another, it will retain the
behavior of the origianl pool type. Use ‘cp’
in order to change file types.
dCache pool files DO
end up on tape. Least recently used file is
deleted first (usually there is no to very
little space available here)
dCache pool files do NOT
end up on tape. dCache tries to keep scratch files for
at least 30 days. Least recently used
file is deleted first. No quotas.
(analysis) dCache pool files do NOT end
up on tape. These files are experiment controlled and will use pool space until
explicitly deleted. This area does fill
up, we may need quotas.
dCache for storing/reading big files –
eventually blue arc will not be available from the worker nodes.
