It must be power of 2 and at least of a kernel page (for Intel x86/x64 processors, this is 4 KiB (8 sectors) This is the granularity in which the mirror is kept to update.
These parameters are only applicable to the raid target: region size has the same meaning and defaults as it does for the raid1 target.Linear, note All the following examples for this target will use 4 1GB4MiB (1961317-sector) disks as /dev/loop0,1,2,3 See for parameters and usage.This is useful for backups.Syntax is: dmsetup message suspend device name Resume, the resume command allows I/O to be submitted to a previously suspended device.New and Changed Features for Red Hat Enterprise Linux.8 Red Hat Enterprise Linux.8 includes the following documentation and feature updates and changes.
A basic /etc/nf need not even exist, when multpath is run without an accompanying /etc/nf, it draws from it's internal database to find a suitable configuration, it also draws from it's internal blacklist.
It is possible to create large, empty, even larger than the pool itself, or sums of objects greater than the pool size, and space isn't allocated until something is actually written to those areas.
Values are P for persistent (survives reboot) and N for non-persistent (invalid upon reboot).
To avoid this, the log may be stored on disk: root #dmsetup create test-mirror -table ' mirror disk 2 /dev/mapper/test-mirror-log0 1024 2 /dev/mapper/test-mirror-data0 0 /dev/mapper/test-mirror-data0 0 1 handle_errors' Its possible to do LVM "-mirrorlog mirror" by creating 2 mirrors: a core mirror for the log.
If after running multipath -ll without a config file, no multipaths are discovered.
The delay target is used is simulated a congested or slow device (like a floppy).
