Hello, I tried to use zfs with zvol and it works great as iscsitarget. I've got a problem with these zvol on initialisation or on reboot. I can reproduce the problem with "zvol volfini" and "zvol init" commands: with 100 zvol I have these results: # time zfs volfini real 0m0.029s user 0m0.006s sys 0m0.019s # time zfs volinit
real 13m23.048s user 0m0.019s sys 0m0.121s I tried to find out where does its time comes from. On dtrace I have a slowup on devfsadm calls. The call is around there: http://cvs.opensolaris.org/source/xref/onnv/onnv-gate/usr/src/lib/libzfs/common/libzfs_dataset.c#3735 Is there a way to make it asynchrone so each zvol initialisation take less time? Thank you, Miro This message posted from opensolaris.org _______________________________________________ storage-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/storage-discuss
