Talk:Logical volume management

From Wikipedia, the free encyclopedia

[edit] LE and other acronyms like PE, PV, and VG

What is an LE? All these acromyms should be explained, or better yet, in an encyclopedia, expanded to thier full form: LV, PE, PV, PVG. The shortened version is easy on the writer, harder on the reader. —Preceding unsigned comment added by Gbeeker (talk • contribs)

I disagree they should be expanded. It would be confusing when using any lvm management tools. A reference section yes, but expanding these in all cases is going to cause confusion to anyone reading and then using lvm utilities. —Preceding unsigned comment added by 199.84.5.210 (talk • contribs)

Also, what is the relationship between Volume Groups (VGs) and Logical Volumes (LVs). —Preceding unsigned comment added by 217.158.168.198 (talk • contribs)

The HOWTO link should be able to explain this in more detail now. What about migrating more info. from the HOWTO into this page? Sasank 04:09, 16 May 2006 (UTC) Is the HOWTO link too linux specific? But I think its worth having it. Sasank 04:11, 16 May 2006 (UTC)

logical extent (LE):
Each logical volume is split into chunks of data, known as logical extents. 
The extent size is the same for all logical volumes in the volume group.

I just moved the Terminology section to the top and expanded it. --Unixguy 13:24, 26 June 2007 (UTC)

[edit] Random notes

There is no "SAN LUN". LUN is defined by either SCSI or FCP protocol. 20 years ago nobody heard of SAN, but each SCSI disk or SCSI RAID array reported one or more LUNs.

The fact that VG can be offlined/onlined/exported/imported as a unit is THE REASON the whole VG idea exists in the first place. If these four operations were unneccessary or unimportant, then LVs should be allowed to share whole PV space. It would be better, simpler, more effective design. But it's not. —Kubanczyk 05:41, 21 June 2007 (UTC)

Both are fair points. I've also noticed you've added some helpful bits about mirroring. I folded your changes back into the main text, but for some reason, you reverted my edits as vandalism. —Ghakko 13:22, 22 June 2007 (UTC)

WTF do you mean "folded into the main text"?!?! On the Logical volume management you've just reverted other people's valid edits (including mine) and rewritten them on your own. I provided a link to Help:Reverting, which you ignored. It states clearly Do not revert good faith edits. Another quote If you feel the edit is unsatisfactory, improve it rather than simply reverting or deleting it! You've failed to understand Wikipedia policy on reverts and you've proven it by reverting once again. I'm walking away hoping that one day you will get a clue... --Kubanczyk 05:43, 25 June 2007 (UTC)

[edit] Doesn't Vista add Allocate anywhere?

I am not sure but doesn't Vista allow growing/spanning of LV and allocating unallocated space to any PV? —Preceding unsigned comment added by 221.128.180.131 (talk) 16:11, 5 October 2007 (UTC)
