Don't use the discard mount-options because, as you mention, it can decrease performance in the moment. The preferred solution is to run 'fstrim' automatically in an off-peak time, eg. the middle of the night. It'll discard all the unused blocks in one go. _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
