Last time your patches to fix this problem looks kind of easy, why 'a lot of work' now? > $ ./farm.sh simple > using backend simple store > Name Id Size Used Shared Creation time VDI id Tag > test 1 100 GB 100 GB 0.0 MB 2012-08-23 11:29 7c2b25 > > real 0m1.016s > user 0m0.092s > sys 0m0.000s This looks much better, but I think not good enough. If we have 500G data, it seems that we still need around 5 minutes, which is unacceptable to guest VM too. For example Linux guests won't tolerate for more than 2 minutes. I think we really need to put the moving stale objects job to worker thread as a long-term fix, which never block main thread. -- thanks, Yuan -- sheepdog mailing list sheepdog@lists.wpkg.org http://lists.wpkg.org/mailman/listinfo/sheepdog
