s-kaczmarek's questions

This is my first nfs / autofs configuration, so I probably configured something wrong. When I navigate to directory, which I added to /etc/auto.master I can't see any mount points, but when I issue cd with full path to expected mount point, than it tunes out, that I can access it. I think, that outputs below are self explanatory:

user@user-desktop:~/mnt/shares/autofs$ ls
user@user-desktop:~/mnt/shares/autofs$ ls ./backup_tmp
lost+found  test.file

This is how /etc/auto.master file looks like (on the receiver machine). First two lines comes by default, so I was not sure if I should touch them:

+dir:/etc/auto.master.d
+auto.master
/home/user/mnt/shares/autofs /etc/auto.misc --timeout=20

And this is how /etc/auto.misc looks like (first line comes by default):

cd      -fstype=iso9660,ro,nosuid,nodev :/dev/cdrom
data_archive           -fstype=nfs4     192.168.1.140:/mnt/data_archive
data_file-resources    -fstype=nfs      192.168.1.140:/mnt/data_file-resources
backup_tmp             -fstype=nfs      192.168.1.140:/mnt/backup_tmp

Can anyone please help me debug this problem?

I'm little confused, because I found two different instructions about creating RAID0 with LVM. First resource shows way of creating RAID0 wit this pattern:

lvcreate -i[num drives] -I[strip size] -l100%FREE -n[lv name] [vg name]

but looking into official manual, it shows little different approach to do, at least I think, the same task.

lvcreate --type raid0  [--stripes Number --stripesize Size] VG [PVs]

In the second example, we tell explicitly that we are dealing with raid0. I'm not sure now, which pattern is correct. I tried first one and created lvg without problems, but not tested yet deeper.

There is also second question I would like to ask before I mess up my computer ;)

I have two same ssd drives - I want to speed up my performance of system and games. I want to make RAID 0 out of them and recently, I found article saying that it could be done with LVM.

I'm quite surprised, that setting this raid is made on the last "layer" of LVM - logic group. I would expect it to happen on the level of creating volume groups and then create normal partitions on top of raid 0.

Just to make sure, is this going to work well?

sudo lvcreate -i2 -I4 --size 100G -n root lvm-system /dev/sda /dev/sdc 
sudo lvcreate -i2 -I4 --size 4G -n swap lvm-system /dev/sda /dev/sdc 
sudo lvcreate -i2 -I4 -l 100%FREE -n games lvm-system /dev/sda /dev/sdc

I would appreciate any help!
