Hello,
what does the mount option ‘async’ / ‘sync’ do?
Are SATA disks operate usually in sync mode? Filesystem is ext4.
Do i force asynchronious mode with the mount option ‘async’?
Which role has the libaio-package?
Best regards
AKl
This is w hat the man page says:
sync
All I/O to the filesystem should be done synchronously. In case of media with limited number of write cycles (e.g. some flash drives) “sync” may cause life-cycle shortening.
II detect from the man page also that async is the default. Thus why to "force’ it?
And I find there:
Some of these options could be enabled or disabled by default in the system kernel. To check the current setting see the options in /proc/mounts.
The following options apply to any filesystem that is being mounted (but not every filesystem actually honors them - e.g., the sync option today has effect only for ext2, ext3, fat, vfat and ufs):
