Description
For some reason, running ntfclone causes excessive I/O and CPU utilization
and brings the machine to its knees.
Need to investigate why.
Speculation: ntfsclone writes completion percentages to stdout continuously.
stdout gets redirected to a file under /var/log/ganeti/os/ causing excessive I/O.
Investigate possible use of a '--quiet' flag.
History
#1 Updated by Vangelis Koukis almost 13 years ago
- Status changed from Assigned to Closed
This has been patched temporarily to redirect to /dev/null, to reduce the load incurred by the verbose progress reporting, committed to the win-support branch of the local Ganeti Instance Image repository.
For a long-term solution, a patch enabling use of --quiet has been developed, and will be pushed upstream.
Closing ticket.
