The log section can be either separate from the data section or contained within it. 0, sync is the default, and async must be explicitly requested if needed. If you are going to use a software RAID, it is recommended to use a chunk size of 128k as starting point, depending on the workload you are going to run. This applies to all filesystem types. You can then copy over only needed files post-restore for a surgical <dir> – The directory that is to act as the mount point for the filesystem. The value By default, the /etc/fstab file is processed before the initiator starts. But the reasoning for more security-focused situations is as follows. For example I use ext4 and set largefile4 and noatime. 0. mkdir option makes mount create a The fstab file allows you to specify how and what options need to be used for mounting a particular device or partition, so that it will be using that options every time you mount it.

A network file system (NFS) mounted from a certified network-attached storage (NAS) device. The volumeBindingMode field controls when volume binding and dynamic provisioning should occur. Solved. Using the discard option for a mount in /etc/fstab enables continuous TRIM in device operations: /dev/sda1 / ext4 defaults,discard 0 1 Note: Specifying the discard mount option in /etc/fstab does not work with an XFS / partition. relatime - The default atime behaviour is relatime, which has almost no overhead compared to noatime but still maintains sane atime values. I cannot imagine what should go worse with such a fallback attempt. The writer of that page is simply using nodev as a shorthand for "no device" - as a dummy If the device exports stripe geometry information, the mkfs utility (for ext3, ext4, and xfs) will automatically use this geometry. If the fallback works to get the backup restored things should be OK, if not "rear recover" behaves as before I want to know what's the best practices for file system and mount options to set this path for achieve better performance. There are no issues with EXT4 volumes and with mounting XFS in RO. To set up shares with extended access control list (ACL) support, the file system hosting the share must have the user and system xattr name space enabled. As a result, whatever is specified in the "device" parameter, like nodev in your case, is completely ignored. As you can see in your mount output, nobarrier option is not used. I can't find documentation about seclabel. Using this methodology, you do not have to specify multiple file system mount points for the database storage.

Common Mount Options; Option Description ; async: Allows the asynchronous input/output operations on the file system. This can lead to The following XFS-specific mount options may be used when mounting an XFS filesystem. Mounting a file system with noatime ensures that no access time is updated on it, irrespective of file attributes. allocsize=size Sets the buffered I/O end-of-file preallocation size when doing delayed allocation writeout (default size is 64KiB). == Mount options === Inode allocation. Setting the A attribute on a file ensures that its access time is never updated, irrespective of mount options. Run # mkfs. Then edit /etc/fstab and fix the incorrect option.

When you create a custom image of an instance where the volumes, excluding the root volume, are listed in the /etc/fstab file, instances will fail to launch from the custom image. File system . ext4, fat, vfat, ufs and xfs): async All I/O to the filesystem should be done asynchronously. change data-root to somewhere The systemd fstab generator, used to mount the root filesystem, only takes into account the mount options specified in the kernel command line through the "rootflags=" variable. In some cases this is not sufficient (for example network block device based mounts, such as iSCSI), in which case _netdev may be added to the mount option string of the unit, which forces systemd to consider the XFS mount options. After the installation is complete, It was expected that the xfs partition should have noatime,pquota mount options, but the mount options in the /etc/fstab file show only noatime, without pquota.
