1. Create partitions to be used and initialize them as physical volumes.
2. Create a volume group.
3. Create a logical volume.
4. Create a file system on a logical volume.

Ndiyisusa njani ivolumu yengqiqo?

Ukususa umthamo ongasebenziyo wengqiqo, sebenzisa umyalelo welvremove. Ukuba umthamo wengqiqo uxhonyiwe ngoku, yehlisa ivolyum phambi kokuba uyisuse. Ukongeza, kwindawo edibeneyo kufuneka uvale umthamo onengqondo ngaphambi kokuba ususwe.

Uwususa njani umthamo womzimba kwiqela levolumu?

Ukususa imiqulu engasetyenziswanga kwiqela levolumu, sebenzisa umyalelo we-vgreduce. Umyalelo we-vgreduce ucutha umthamo weqela levolyum ngokususa umthamo womzimba omnye okanye ngaphezulu ongenanto. Oku kukhulula loo mithamo ebonakalayo ukuba isetyenziswe kumaqela omthamo ahlukeneyo okanye ukuba isuswe kwinkqubo.
