+==USB disks go stale==
-oSometimes USB disks go stale after a time of non use. 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
+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 > $foo; done
+==Samba==
+Restart: "sudo /etc/init.d/smbd restart"
+Conf file: "/etc/samba/smb.conf"
+Example disk config:
+  [bigdisk1]
+  path = /bigdisk1
+  valid users = sonata
+  read only = no
+  [bigdisk2]
+  path = /bigdisk2
+  valid users = sonata
+  read only = no
+  [bigdisk3]
+  path = /bigdisk3
+  valid users = sonata
+  read only = no
+  [sonata20160730-20180110]
+  path = /sonata20160730-20180110
+  valid users = sonata
+  read only = yes
+==List samba disks==
+smbtree
+example:
+  root@bserve1:/etc/samba# smbtree
+  Enter root's password:
+  WORKGROUP
+	\\BSERVE1        		bserve1 server (Samba, Ubuntu)
+		\\BSERVE1\IPC$           	IPC Service (bserve1 server (Samba, Ubuntu))
+		\\BSERVE1\sonata20160730-20180110
+		\\BSERVE1\bigdisk3
+		\\BSERVE1\bigdisk2
+		\\BSERVE1\bigdisk1
+		\\BSERVE1\print$         	Printer Drivers
+==STORE1==
+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
