DISASTER RECOVERY
  1. Install a new server.
  2. Load RHEL - currently using RHEL AS 3.
  3. Install updates using up2date.
  4. Check NFS exports.
  5. Check SAMBA configuration and status.
  6. Make sure you select DNS and DHCP servers on the software installation screens.
  7. Copy over backup files from alpha:/home/backups/dns (these files are rsync'd daily).
  8. Make sure named, dhcpd, and nscd are started.
  9. (install firestarter).
  10. Install netvault.
Additional, non-critical items to take care of:
  1. Install APCUPSD (it is in /usr/local/src which is backed up to alpha).

SAMBA NOTES 09-11-18

Starting with Samba 3.4, the default passdb password backend has been changed to 'tdbsam.' If you're still using the old password setup with the 'smbpasswd' backend this will break it. If you've been using a standalone Samba server, chances are good that's what you've been using for security. If you want to stick with it, simply enter the line: passdb backend = smbpasswd in your smb.conf. You're better off in the long run though if you convert your smbpasswd entries into tbdsam by running 
pdbedit -i smbpasswd -e tdbsam
from a Linux shell. The tdbsam offers you more options for users setting, and there are some advanced server commands which won't work with the 'smbpasswd' backend.

If you've set up your Samba boxes properly--e.g. you can reach your shared drives just fine from an XP box or a Mac - but you still can't see them from Windows 7, you'll need to do fixing. Go to your Windows 7 box and try going to: Control Panel - Administrative Tools - Local Security Policy Local Policies - Security Options. Once there, set "Network security: LAN Manager authentication level" to "Send LM & NTLM responses" and the "Minimum session security for NTLM SSP" to "Disable Require 128-bit encryption."

On Vista, it's a little more complicated. Here, you'll need to click "Start -> Run." Once you're at Vista's idea of a command line, type in the Run field: "secpol.msc." That will bring you to Vista’s security policy system. Once there, use "Go to: Local Policies > Security Options" and then find "Network Security: LAN Manager" authentication level. Now change the Setting from "Send NTLMv2 response only" to "Send LM & NTLM - use NTLMv2 session security if negotiated."

Previous install failed when trying to do a full backup with error about no acl support, so tried: 
rpmbuild --rebuild --define "build_client_only 1" --define "nobuild_gconsole 1" bacula-3.0.1-1.src.rpm
Failed with errors about "error: Installed (but unpackaged) file(s) found".

I copied the bacula.spec file from /usr/src/redhat/SPECS/bacula.spec to /usr/local/src/bacula and editted it to add the following lines: 

>*** 1899,1904 ****

The disks /dev/sdd and /dev/sde didn't have valid partition tables for some unknown reason. Since /dev/sde didn't have any parts of it in use (pvdisplay /dev/sde), I was able to run the command "vgreduce VG00 /dev/sde" to remove sde from the volgrp. I then used fdisk to partition the drive into one partition of type "8e" (lvm) and then ran the following commands to recreate the volgrp, logical volumes, and partitions.

The plan is to use rsync to sync the current partitions with the new ones and then eventually mount the new ones as the live ones. Then I will be able to fix the partition table on /dev/sdd and use it for a new volgrp or add it to VG01.

After installing the new Apple Fiber channel cards (HBAs) in both alpha and mail and rebooting, the HBAs were "dead" even though they were recognized as new hardware on the re-boot and the drivers were installed. Turns out I needed to:
  1. Modify /etc/modules.conf to add two lines at the end:
    alias eth0 e1000
    alias eth1 e1000
    alias scsi_hostadapter aic7xxx
    alias scsi_hostadapter1 gdth
    alias usb-controller usb-uhci
    alias block-major-43 off
    alias scsi_hostadapter2 mptbase
    alias scsi_hostadapter3 mptscsih
  2. Make copies of /boot/initrd-2.4.21-37.EL.img and /boot/initrd-2.4.21-37.ELsmp.img
  3. Run the following commands to make new initrd (initial RAM disk images) with the drivers installed:
    [root@mail boot]# mkinitrd -v -f /boot/initrd-2.4.21-37.EL.img 2.4.21-37.EL
[root@mail boot]# mkinitrd -v -f /boot/initrd-2.4.21-37.ELsmp.img 2.4.21-37.ELsmp
  4. I then rebooted and the HBAs were recognized.

According to a search on the web:
Samba 3 uses both port 139 and 445. So using Windows 2000 or better the computer tries to connect to both ports and just drops one using "RST". Hence samba still things the client is there and needs a little bit of time to sort this out. As we do not use Port 445 (new one) we just disabled this and got rid of all the messages. Nevertheless it is nothing to worry about - if you do not mind you log being filled up with things you can ignore this.

 Due to a space shortage on the mailserver, I moved some data to alpha and put it on one of the logical volumes I had previously created. The VolGrp that the LogVol was on consisted of two disks (/dev/sdc1 and /dev/sdd1). It appears one of the disks is corrupt and I started getting I/O use of 100% on both alpha and the mail server (which had the LogVol mounted). managed to restore /mail/home2 from tape to /home/mailhome2 on alpha and then NFS mount that onto the mailserver (/mail/home2) and physics (/mail/home2). I still need to physically remove the bad drive. It just is very slow.

Turned on nscd (name service caching daemon (chkconfig --level 345 nscd on, service nscd start). This service runs in the background and keeps a copy of /etc/passwd, /etc/group, and /etc/hosts files in memory. This can aid performance by reducing disk read overhead on a heavily loaded system dealing with many logins or name resolution requests.

 Major failure of RAID array on the 1st. Disk started rebuilding array to spare drive but it eventually failed and array went offline. 

Turning on quotas:

1. Edit /etc/fstab for the partition you want to turn quotas on for, add usrquota after the word defaults, like this
/dev/hda1               /backup                 ext3    defaults,usrquota 1 2
2. Reboot your computer
3. run this
/sbin/quotacheck -guvamf -F vfsv0
4. run this (just in case)
/sbin/quotacheck -guvamf -F vfsold
5. Turn on the quotas
/sbin/quotaon -a
and that is it...

Unexpected hang:  This morning people were reporting network problems but I quickly determined it was that the home dirs were not available.  Could ping alpha but could not login or mount nfs/smb shares.  Went to machine room and it was hung, no messages about why.  I rebooted and fsck'd all filesystems then rebooted OK.  /home took almost exactly 1/2 hour to fsck.  I turned hyperthreading off in BIOS.  No indication in logs as to why it hung.  Refernece info:

NFS ERRORS:  I am seeing NFS errors from some of the clients (www).  Need to check this out...
Fixed apcupsd error:  From /var/log/messages:
Jun 29 04:17:45 www kernel: (see the NOTES section of 'man 2 wait'). Workaround activated.
Jun 29 04:18:51 www kernel: application bug: apcupsd(648) has SIGCHLD set to SIG_IGN but calls wait().
I downloaded the latest release (not stable) of apcupsd and installed it (apcupsd 3.10.6 (30 May 2003)).  Seemed to fix the problem.  Did the same fix on alpha.  

03-02-25
- Received new carrier for RM8000.  Installed it, and Power light and Disk lights came on.  After 34 seconds, Disk light went out indicating there was no drive installed or the drive has failed.  Bob at promise wanted me to move one of my good disks there but I refused since it would mean my array would go critical and it would take many hours to rebuild it.  Just after lunch there was a power surge and two UPS units got fried including the one for alpha.  After repowering the RM8000, slot 7 came alive!
03-02-20
- Received RMA replacement disk.  Maxtor 4G160JB, s/n V2004685.  Date of manufacture: 2001/12/22.
03-02-15
- Copied all data from /www, /newton, /home2, /home to mailx r raid array.  Deleted, then re configured array to be RAID 5 with a hot spare drive.  After ~40% initialization, drive 7 failed and rebuild started to include hot spare (disk 6).  Eventually that finished, then re-initializing of the initial array restarted.  It took many hours.   Used fdisk to create partitions.  Created filesystems using command
mkfs.ext3 -v -L /home /dev/sda1, etc.  
03-02-05
- Replaced failed disk with Maxtor DiamondMAX 16, S/N A605QE7E.  Started rebuild (automatic) and 3:05pm.  At 4pm it wasa approx 5% finished.  However, a backup is taking place at the same time. Rebuild finished sometime during the night so must have been slowed a lot by the backup.
03-02-04
- Maxtor disk SN G804EZQE in slot 7 failed.
2002 - 09-12

- Promise UltraTrak RM8000 SCSI/ATA RAID array.  Used fdisk to partition the disk as follows:
Disk /dev/sda: 255 heads, 63 sectors, 138718 cylinders
Units = cylinders of 16065 * 512 bytes
