Description: |
| 7 |
- install & configure pppoe(ADSL) |
| 8 |
- ext3 shortcuts |
| 9 |
- LVM (Logical Volume Manager) shortcuts |
| 10 |
|
| 11 |
|
| 12 |
FIRST CHECK if |
| 13 |
kernel with built-in(boot ext3 or lvm!) or module supported ext3 and lvm is running! |
| 14 |
|
| 15 |
- EXT3: |
| 16 |
- convert fs to ext3 |
| 17 |
tune2fs -j /dev/sdaXX |
| 18 |
- create new ext3-fs (normally already done in default-(guided)-setup) |
| 19 |
mke2fs -j /dev/sdaXX |
| 20 |
- auto-check-every-n-mounts/days/seconds |
| 21 |
tune2fs -i 0 /dev/sdaXX |
| 22 |
|
| 23 |
- Mouse: |
| 24 |
- Install packet "gpm" |
| 25 |
|
| 26 |
- ADSL: |
| 27 |
- Install packet "pppoe" and "pppoeconf" |
| 28 |
- Run "pppoeconf" or |
| 29 |
- Edit /etc/ppp/peers/dsl-provider (modify "user"-entry) |
| 30 |
- Edit /etc/ppp/pap-secrets (add entry) |
| 31 |
- Connect with "pon dsl-provider" or use start-stop script at /etc/init.d/ppp |
| 32 |
- Disconnect with "poff dsl-provider" or use start-stop script at /etc/init.d/ppp |
| 33 |
|
| 34 |
- LVM |
| 35 |
- install packet "lvm(>>0.9)" and "lvm-common" |
| 36 |
(currently not in the Debian/testing(woody) package-set, |
| 37 |
search it at the unstable sets!) |
| 38 |
|
| 39 |
- create LVM-partitions with "fdisk /dev/sdx" |
| 40 |
- "d" and partition-nr "y" for delete partition "sdxy" |
| 41 |
- "n" and parition-nr "y" for add partition "sdxy" |
| 42 |
- "t" partition-nr "y" and hex-code "8e" for |
| 43 |
change /dev/sdxy to LVM partition-type |
| 44 |
- "w" for write partition table and quit |
| 45 |
|
| 46 |
- do a "pvcreate /dev/sd[ce]1" |
| 47 |
For testing purposes you can use more than one partition on a disk. |
| 48 |
You should not use more than one partition because in the case of |
| 49 |
a striped LV you'll have a performance breakdown. |
| 50 |
|
| 51 |
- do a "vgcreate test_vg /dev/sd[ce]1" to create the new VG named "test_vg" |
| 52 |
which has the total capacity of both partitions. |
| 53 |
vgcreate activates (transfers the metadata into the LVM driver in the kernel) |
| 54 |
the new volume group too to be able to create LVs in the next step. |
| 55 |
|
| 56 |
- do a "lvcreate -L1500 -ntest_lv test_vg" to get a 1500MB linear LV named |
| 57 |
"test_lv" and it's block device special "/dev/test_vg/test_lv". |
| 58 |
|
| 59 |
Or do a "lvcreate -i2 -I4 -l1500 -nanother_test_lv test_vg" to get a 100 LE |
| 60 |
large logical volume with 2 stripes and stripesize 4 KB. |
| 61 |
|
| 62 |
- For example generate a ext3 filesystem in one LV with |
| 63 |
"mke2fs -j /dev/test_vg/test_lv" and mount it. |
| 64 |
|
| 65 |
- extend /dev/test_vg/test_lv to 1600MB with relative size by |
| 66 |
"lvextend -L+100 /dev/test_vg/test_lv" |
| 67 |
or with absolute size by |
| 68 |
"lvextend -L1600 /dev/test_vg/test_lv" |
| 69 |
|
| 70 |
- reduce /dev/test_vg/test_lv to 900 logical extents with relative extents by |
| 71 |
"lvreduce -l-700 /dev/test_vg/test_lv" |
| 72 |
or with absolute extents by |
| 73 |
"lvreduce -l900 /dev/test_vg/test_lv" |
| 74 |
|
| 75 |
- rename a VG by deactivating it with |
| 76 |
"vgchange -an test_vg" # only VGs with _no_ open LVs can be deactivated! |
| 77 |
"vgrename test_vg whatever" |
| 78 |
and reactivate it again by |
| 79 |
"vgchange -ay whatever" |
| 80 |
|
| 81 |
- rename a LV after closing it by |
| 82 |
"lvchange -an /dev/whatever/test_lv" # only closed LVs can be deactivated |
| 83 |
"lvrename /dev/whatever/test_lv /dev/whatever/whatvolume" |
| 84 |
or by |
| 85 |
"lvrename whatever test_lv whatvolume" |
| 86 |
and reactivate it again by |
| 87 |
"lvchange -ay /dev/whatever/whatvolume" |
| 88 |
|
| 89 |
- if you own Ted Tso's/Powerquest's resize2fs program, you are able to |
| 90 |
resize the ext2 type filesystems contained in logical volumes without |
| 91 |
destroyiing the data by |
| 92 |
"e2fsadm -L+100 /dev/test_vg/another_test_lv" |
| 93 |
|
| 94 |
