New Allen Telescope Array Development

Sometimes USB disks go stale after a time of non use. This was happening a lot on churn1, but also on other computers occasionally. The trick it to tell the disks not to do that. Write a little script and run it as root:

for i in /sys/bus/usb/devices/*/power/autosuspend; do echo 2 > $i; done 
for foo in /sys/bus/usb/devices/*/power/level; do echo on > $foo; done 

Restart: “sudo /etc/init.d/smbd restart”

Conf file: “/etc/samba/smb.conf”

Example disk config:

[bigdisk1]
path = /bigdisk1
valid users = sonata
read only = no

[bigdisk2]
path = /bigdisk2
valid users = sonata
read only = no

[bigdisk3]
path = /bigdisk3
valid users = sonata
read only = no

[sonata20160730-20180110]
path = /sonata20160730-20180110
valid users = sonata
read only = yes

smbtree

example:

root@bserve1:/etc/samba# smbtree
Enter root's password: 
WORKGROUP
\\BSERVE1        		bserve1 server (Samba, Ubuntu)
	\\BSERVE1\IPC$           	IPC Service (bserve1 server (Samba, Ubuntu))
	\\BSERVE1\sonata20160730-20180110	
	\\BSERVE1\bigdisk3       	
	\\BSERVE1\bigdisk2       	
	\\BSERVE1\bigdisk1       	
	\\BSERVE1\print$         	Printer Drivers

Early August Daniel set up the 90TB RAID5 disk system.

/etc/fstab entry:

//10.10.1.140/store1 /store1 cifs username=sonata,password=polaris,iocharset=utf8,sec=ntlm,vers=1.0 0 0

The /etc/samba/smb.conf entries:

[store1]
  comment = store1's large raid array
  path = /datax
  guest ok = yes
  writeable = yes
  write list = sonata, root
  valid users = sonata
  read only = no
  create mode = 0777
  force create mode = 0777
  directory mask = 0777
  force directory mode = 0777
