Define a cgroup that limits the I/O bandwidth to 50MB/s when
reading from /dev/sda1
.
mount { blkio = /cgroup/iolimit; } group iocap1 { blkio { # Limit reads from /dev/sda1 to 50 MB/s blkio.throttle.read_bps_device="8:1 52428800"; } }
Define a cgroup that limits the number of read transactions to
100 per second when reading from /dev/sdd
.
mount { blkio = /cgroup/iolimit; } group iocap2 { blkio { # Limit read tps from /dev/sdd to 100 per second blkio.throttle.read_iops_device="8:48 100"; } }
Define two cgroups
with different shares of
I/O access to /dev/sdb
.
mount { blkio = /cgroup/iolimit; } # Low access share group group iolo { blkio { # Set the share of I/O access by /dev/sdb to 25% blkio.weight_device="8:16 250"; } } # High access share group group iohi { blkio { # Set the share of I/O access by /dev/sdb to 75% blkio.weight_device="8:16 750"; } }
