Hello,
I'm a french user of a Mandrake 8.2 distribution. I notice a little error in
the man of lvcreate command. So, here is what I suggest.
Original man
-p, --permission r/w
Set access permissions to read only or read and write.
Default is read and write.
May be
-p, --permission r/rw
Set access permissions to read only or read and write.
Default is read and write.
Because if I use
# lvcreate -L 4064m -n fpodlv -p w fpodvg
I obtain
lvcreate -- ERROR option p argument "w"
And if I try
# lvcreate -h
I obtain (extract)
[-p|--permission {r|rw}]
I've got another question. I precise I'm not a realy experienced user under
Linux but I try to make a solution to backup systems with a easy to use
interface called "fpod". This project drives me to use the LVM facilities.
I intended to create a big LV on a RAID array of 500 GB. Further this space
could be extended to much more RAID array in the same LV. I notice in the
vgcreate's man a kernel limit to 2 TB per block device.
But, when I test the LVM tools, I obtain a maximum logical volume size of
1.00 Terabyte after the command :
# vgcreate -s 32m fpodvg /dev/scsi/host0/bus0/target1/lun0/part1
If I try :
# vgcreate -s 16m fpodvg /dev/scsi/host0/bus0/target1/lun0/part1
I obtain
vgcreate -- INFO: maximum logical volume size is 1023.97 Gigabyte
So, my question is : does 2 TB in place of 2 TeraByte or 2 TeraBlock ?
LV' = 16 MByte x 65536 = 1 TeraByte = 2 TeraBlock (if 1 Block = 512 KByte)
LV" = 32 MByte x 65536 = 2 TeraByte = 4 TeraBlock (out of range)
Thanks for your attention.
Good day,
Estienne Bloch.
