What is Max logical volume size?
Table A-1 Volume Group Version Maximums
| Version 1.0 Volume Groups | Version 2.1 Volume Groups | |
|---|---|---|
| Maximum size of a physical volume | 2 TB | 16 TB |
| Maximum size of a volume group | 510 TB | 2048 TB |
| Maximum size of a logical volume | 16 TB | 256 TB |
| Maximum size of a physical extent | 256 MB | 256 MB |
How do I change PPs to Max PV?
The MAX PPs per VG value can be increased dynamically against an active (imported/varied on) Volume Group. The new value must be greater than the existing value. Once increased, the value cannot be decreased without removing and recreating the VG. Enter the VG name and change the following entry to the desired value…
What is PE size in Linux?
PE Size – Physical Extends, Size for a disk can be defined using PE or GB size, 4MB is the Default PE size of LVM.
What is the maximum size of a single LV?
What is the maximum size of a single LV? The answer to this question depends upon the CPU architecture of your computer and the kernel you are a running: For 2.4 based kernels, the maximum LV size is 2TB. For some older kernels, however, the limit was 1TB due to signedness problems in the block layer.
Which of the following commands can be used to format a disk partition as ext4?
mkfs.
An alternate filesystem may be used by running a different format command. To format the partition using ext4, run the command mkfs. ext4 /dev/vdb1 .
What is T factor in AIX?
Using the “t-factor” This factor will multiply the number of PPs per PV by 1016 to reach a higher maximum number of PPs each PV could have. The downside of using the t-factor is it divides the maximum number of PVs that can be put in to a volume group.
How do you change the size of a PE?
to move the extents 103680-221247 to 0-103679 on the physical volume /dev/sdc1 . You might need to move segments in steps. Use pvdisplay –maps /dev/sdc1 to show what extents are allocated on the physical volume /dev/sdc1 .
What is PE in logical volume?
Each physical volume is divided chunks of data, known as physical extents, these extents have the same size as the logical extents for the volume group.
Which of the following commands is used to partition a hard disk?
fdisk also known as format disk is a dialog-driven command in Linux used for creating and manipulating disk partition table. It is used for the view, create, delete, change, resize, copy and move partitions on a hard drive using the dialog-driven interface.
How many physical volumes can be added to a volume group?
If the 1016 PP/PV limit is maintained, you can add up to 32 physical volumes in a standard volume group or up to 128, if it is a “BIG” volume group. The chvg command also has a -t flag to allow you to change the max PPs/PV limit on an existing volume group, so that a larger drive could be added at that point.
Is there limit to number of physical partitions per volume?
The disadvantage is that increasing the number of PPs allowed per disk will limit the number of disks allowed in the volume group. If the 1016 PP/PV limit is maintained, you can add up to 32 physical volumes in a standard volume group or up to 128, if it is a “BIG” volume group.
What’s the maximum number of FlexVol volumes per node?
In ONTAP 9.4 and later, a volume can contain up to 1023 Snapshot copies. Beginning in ONTAP 9.7, the maximum supported number of FlexVol volumes on AFF platforms with at least 128 GB of memory has increased to 2,500 FlexVol volumes per node; however, only 1,000 volumes per node can be active (primary workloads) at one time.
What is the maximum size of infinite volumes?
1.33 TB * number of nodes used 1.33 TB * number of nodes used This size is approximate due to rounding. Infinite Volumes Maximum size 20 PB 20 PB
