Patch Set 1: I think this may be the the root cause for network disconnects when copying disks on block storage - once the copy finish we wipe the old disks, mixing crazy amount of io (multiple dd processes pushing zeros to storage), and doing millions of syscalls, looping over poll(), waitpid() epoll() in AsyncProc etc. Needs more testing, but I have seen too many disconnect lately when testing disk copies,and vdsm is always running with very high cpu usage during this time. -- To view, visit https://gerrit.ovirt.org/57541 To unsubscribe, visit https://gerrit.ovirt.org/settings Gerrit-MessageType: comment Gerrit-Change-Id: I7f5ec5faefb6840f1bd5348b93cc784d0aff8690 Gerrit-PatchSet: 1 Gerrit-Project: vdsm Gerrit-Branch: master Gerrit-Owner: Nir Soffer <[email protected]> Gerrit-Reviewer: Adam Litke <[email protected]> Gerrit-Reviewer: Allon Mureinik <[email protected]> Gerrit-Reviewer: Dan Kenigsberg <[email protected]> Gerrit-Reviewer: Freddy Rolland <[email protected]> Gerrit-Reviewer: Idan Shaby <[email protected]> Gerrit-Reviewer: Jenkins CI Gerrit-Reviewer: Nir Soffer <[email protected]> Gerrit-Reviewer: Piotr Kliczewski <[email protected]> Gerrit-Reviewer: Yaniv Bronhaim <[email protected]> Gerrit-Reviewer: gerrit-hooks <[email protected]> Gerrit-HasComments: No _______________________________________________ vdsm-patches mailing list [email protected] https://lists.fedorahosted.org/mailman/listinfo/vdsm-patches
