NFS help

lleb · 06-28-2009, 07:29 PM

Hello everyone, thanks for looking at this thread and thanks in advance for any help you can provide.

background on the setup and hardware configuration:

I am running CentOS 5.3 with the 2.6.18-128.1.14.e15

I have added the extra hdd to fstab, they auto mount properly, well permissions might be off from my goal but they mount. its a start.

Code:

df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda2              48G  1.3G   44G   3% /
/dev/sda1             251M   21M  217M   9% /boot
tmpfs                1014M     0 1014M   0% /dev/shm
/dev/sda3             133G  188M  126G   1% /home1
/dev/sdb2              71G  180M   67G   1% /home11
/dev/sdc1              20G   13G  6.7G  66% /winXP
/dev/sdc2             260G  196G   65G  76% /winXP_data
/dev/sdd3              18G   12G  6.0G  66% /sdd3
/dev/sdd4             208G  155G   43G  79% /sdd4

I want every drive and file system (not including / /boot /swap) fully accessible to the network. I just need an internal file server for my 2 iMACs. I am running out of space on them.

Code:

cat /etc/fstab 
LABEL=/1                /                       ext3    defaults        1 1
LABEL=/boot1            /boot                   ext3    defaults        1 2
tmpfs                   /dev/shm                tmpfs   defaults        0 0
devpts                  /dev/pts                devpts  gid=5,mode=620  0 0
sysfs                   /sys                    sysfs   defaults        0 0
proc                    /proc                   proc    defaults        0 0
LABEL=SWAP-sdb1         swap                    swap    defaults        0 0
/dev/sda3		/home1			ext3	rw,noatime,user	0 0
/dev/sdb2		/home11			ext3	rw,noatime,user	0 0
/dev/sdc1		/winXP			vfat	rw,noatime,user,umask=0	0 0
/dev/sdc2		/winXP_data		ntfs-3g	rw,umask=0000,defaults	0 0
/dev/sdd3		/sdd3			ext3	rw,noatime,user	0 0
/dev/sdd4		/sdd4			ext3	rw,noatime,user	0 0

Not sure if those permissions will do what I want. I do not think so.

Code:

cat /etc/exports 
/home1 192.168.2.0/255.255.255.0(rw,insecure)

I added the 'insecure' tag from a suggestion on

http://sial.org/howto/osx/automount/

It worked so far as being able to mount my one share I have setup at the moment, but I was unable to navigate into any of the directories.

Code:

cat /etc/host.allow 
portmap: 192.168.2.0/255.255.255.0

before you ask, yes I did configure the host.allow file to allow all connections from the network.

In the end I will need to mount the following partitions:

/dev/sda3 sdb2 sdc1 sdc2 sdd3 sdd4 with full rwx permissions to anyone on my network.

What changes need I make to get this working. Also how can I reduce any hangtime that might be caused if something gets disconnected due to power loss or an improper umount?

Thanks.

Use the intr option http://www.linuxtopia.org/online_boo...g-options.html in fstab to allow systems to disconnect if it fails

I take it that is client side. is there anything i need to do server side?

Also it looks like only some of the files are not getting proper permissions like lost&found from an old Linux install I had on one of the drives, but most of the rest seem to be up and running from what I can see.

Code:

cat /etc/exports 
/home1 192.168.2.0/255.255.255.0(rw,insecure)
/home11 192.168.2.0/255.255.255.0(rw,insecure)
/winXP 192.168.2.0/255.255.255.0(rw,insecure)
/winXP_data 192.168.2.0/255.255.255.0(rw,insecure)
/sdd3 192.168.2.0/255.255.255.0(rw,insecure)
/sdd4 192.168.2.0/255.255.255.0(rw,insecure)

that is my finished exports file. nice thing about OSx is i just hit command (the apple or windows key) + k and then i type the following:

nfs://192.168.2.100/home11

and poof its mounted and ready for use. Also streams very fast, more then fast enough to stream my movies as that is 90% of what the nfs server will be doing.

then again, it was only the NTFS that allowed my clients to do anything to the files.

I need to be able to create directories, move files in and out, delete files, execute files, mount ISOs etc... on the ext3 partitions.

*bonks head on wall* I've forgotten so much about linux as I have not used it in over a year.

I tried a change to my exports with no luck.

Code:

cat /etc/exports 
/home1 192.168.2.0/255.255.255.0(rw,insecure,no_root_squash,async)
/home11 192.168.2.0/255.255.255.0(rw,insecure)
/winXP 192.168.2.0/255.255.255.0(rw,insecure)
/winXP_data 192.168.2.0/255.255.255.0(rw,insecure)
/sdd3 192.168.2.0/255.255.255.0(rw,insecure)
/sdd4 192.168.2.0/255.255.255.0(rw,insecure)

sadly that did not help with the lack of write permissions to /home1 as i would like. How can I force fstab to mount so the permissions and ownership is for anyone, or at least allow NFS clients ownership to create directories and files?

oh scary. i chmod 777 /home1 as root, now i have full access, is there a better way of doing that?
