I have been playing around with some environmental elements of the shell and began mocking up completions for myself by going into a special directory that had sub-directories named what I needed for my TAB completion. It turns out that with bash it is quite a bit easier and cooler than this.

IBM has given parts of the AIX LVM to Linux, so it would only stand to reason that there is a set of AIX-like commands for linux to use. This shows how to basically create a filesystem. A more comprehensive introduction to LVM is at:
I have created 4 new partitions and got them available to linux for a test:
cd /dev ls brw-r----- 1 root disk 8, 32 Nov 3 10:52 sdc brw-r----- 1 root disk 8, 48 Nov 3 10:52 sdd brw-r----- 1 root disk 8, 64 Nov 3 10:52 sde brw-r----- 1 root disk 8, 80 Nov 3 10:52 sdf
And the LVM command that I find are:
|
lvm lvmchange lvmdiskscan lvmsadc lvmsar |
pvchange pvcreate pvdisplay pvmove pvremove pvresize pvs pvscan |
vgcfgbackup vgcfgrestore vgchange vgck vgconvert vgcreate vgdisplay vgexport vgextend vgimport vgmerge vgmknodes vgreduce vgremove vgrename vgs vgscan vgsplit |
I start with pvcreate:
pvcreate /dev/sdc /dev/sdd /dev/sde /dev/sdf Physical volume "/dev/sdc" successfully created Physical volume "/dev/sdd" successfully created Physical volume "/dev/sde" successfully created Physical volume "/dev/sdf" successfully created
Next I display what I have done:
pvdisplay --- Physical volume --- PV Name /dev/sdb1 VG Name system PV Size 15.00 GB / not usable 0 Allocatable yes PE Size (KByte) 4096 Total PE 3839 Free PE 24 Allocated PE 3815 PV UUID Vydyz4-Njvf-6Wyk-Xl2s-UQM1-VcG4-Gbdk9a --- NEW Physical volume --- PV Name /dev/sdc VG Name PV Size 3.75 GB Allocatable NO PE Size (KByte) 0 Total PE 0 Free PE 0 Allocated PE 0 PV UUID dYMnY2-V4By-N21v-s4Bh-nfMz-TKOp-xrmT2s
I already had one volume created (sdb1) and it clearly shows up a little different. The new
ones all say ‘NEW’ for one thing, and don’t yet show Allocatable, probably because they aren’t associated with a logical volume yet. First, they need a volume group, though:
vgcreate testvg /dev/sdc /dev/sdd /dev/sde /dev/sdf Volume group "testvg" successfully created
And the display command shows what we did:
vgdisplay --- Volume group --- VG Name system System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 2 VG Access read/write VG Status resizable MAX LV 0 Cur LV 1 Open LV 1 Max PV 0 Cur PV 1 Act PV 1 VG Size 15.00 GB PE Size 4.00 MB Total PE 3839 Alloc PE / Size 3815 / 14.90 GB Free PE / Size 24 / 96.00 MB VG UUID F8PeFV-TIJj-YHqB-SpYv-Qxgn-UuwH-yE8eQH
Just like in AIX, the volume group can now be split into logical volumes:
lvcreate --name testlv1 --size 2G testvg Logical volume "testlv1" created lvcreate --name testlv2 --size 2G testvg Logical volume "testlv2" created lvdisplay --- Logical volume --- LV Name /dev/testvg/testlv1 VG Name testvg LV UUID ixjAYJ-A8Uz-CUga-OCmo-HBvv-OaC0-wkR0pN LV Write Access read/write LV Status available # open 0 LV Size 2.00 GB Current LE 512 Segments 1 Allocation inherit Read ahead sectors 0 Block device 253:1
The maps flag is probably something close to AIX’s lsvg -l:
lvdisplay --maps
--- Logical volume ---
LV Name /dev/testvg/testlv1
VG Name testvg
LV UUID ixjAYJ-A8Uz-CUga-OCmo-HBvv-OaC0-wkR0pN
LV Write Access read/write
LV Status available
# open 0
LV Size 2.00 GB
Current LE 512
Segments 1
Allocation inherit
Read ahead sectors 0
Block device 253:1
--- Segments ---
Logical extent 0 to 511:
Type linear
Physical volume /dev/sdc
Physical extents 0 to 511
Even though we can make reference to volume group names (testvg) directly, logical
volumes seem to be named specifically as their device location. To extend and reduce
the size of the logical volume, we have to say:
lvextend -L 2.5G /dev/testvg/testlv2 Extending logical volume testlv2 to 2.50 GB Logical volume testlv2 successfully resized lvreduce -L 2G /dev/testvg/testlv2 WARNING: Reducing active logical volume to 2.00 GB THIS MAY DESTROY YOUR DATA (filesystem etc.) Do you really want to reduce testlv2? [y/n]: y Reducing logical volume testlv2 to 2.00 GB Logical volume testlv2 successfully resized
Next, lets build a filesystem:
mkfs.ext3 /dev/testvg/testlv1
mke2fs 1.38 (30-Jun-2005)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
262144 inodes, 524288 blocks
26214 blocks (5.00%) reserved for the super user
First data block=0
16 block groups
32768 blocks per group, 32768 fragments per group
16384 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912
Writing inode tables: done
Creating journal (16384 blocks): done
Writing superblocks and filesystem accounting information: done
This filesystem will be automatically checked every 28 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
Finally, all we have to do is mount the filesystem and add a line to /etc/fstab for it:
mkdir /test mount /dev/testvg/testlv1 /test df -u (add to /etc/fstab) /dev/testvg/testlv1 /test ext3 rw,noatime 0 0
lsmod Module Size Used by st 68736 0 sr_mod 42916 0 cdrom 64784 1 sr_mod ipv6 464336 32 apparmor 102332 0 aamatch_pcre 34720 1 apparmor loop 41376 0 dm_mod 115288 3 ibmveth 42600 0 sg 69064 0 ibmvscsic 46952 3 pdc202xx_new 32176 0 [permanent] sd_mod 41264 5 scsi_mod 221512 5 st,sr_mod,sg,ibmvscsic,sd_mod
If the module you wanted listed above wasn’t in use, you could unload and load it to refresh:
modproble $modname ; modprobe $modname
First install Steel Bank Common Lisp (sbcl) , it comes in a bz2 file and installs into /usr/local/bin. If you are using something like Ubuntu, dig around with synaptic installer, because all of this is already done for you, and it is really pretty seamless once you get past a few gotchas.
Next make a link from sbcl to lisp as root or through sudo:
cd /usr/local/bin ln -s sbcl lisp
Now download slime and add to your .emacs file. Mine was in my home directory for GNU Emacs 21.3.1:
(add-to-list `load-path "~/slime-2009-04-13") (require 'slime) (slime-setup)
That’s it, you are done, ‘^M (alt on my keyboard) slime’ starts it up.
After playing around with it a little bit, you will realize that ‘asdf’ is really cool so down it too . To install it, just load it up and you are done.
