==Backup/Restore==
===Using a combination of hardware and software compression for tape backup causes errors===
You should use only one of software or hardware compression. Doing both may exercise bugs, and won't reduce the size of data on the tape - it is more likely to increase it.

===Backup to desktop 4GB limit===
As in previous versions of SME Server, the backup to desktop function has a limit of 4GB. It's not fixable until we know where the limit or limits are. All these components are involved in transferring the backup file, and at least one of them is truncating at 4GB: tar, perl, mod_proxy, apache, TCP stack, browser at desktop end. See this bug listing for details [[bugzilla:701]]

In SME 7.4 the 4GB limit is effective when using Windows Internet Explorer, however using a browser such as Mozilla's Firefox the 4 GB does not apply and 180 GB has been successfully achieved in a backup-to-desktop. See [[bugzilla:5222]] for more information.

===Boot failure after install if you have enabled hardware raid===
There sometimes seem to be conflicts with the SME Server automatic software raid setup in combination with hardware raid. Disabling the hardware raid in your motherboard or controller card's bios is the suggested fix. <!--- See these bug reports for details:

===aic7xxx driver hangs on installation boot===
On some Compaq Proliant servers (specifically an ML370 G2), & possibly others, the aic7xxx driver will hang if there is nothing connected to the adaptor or if it is not terminated correctly. On most Proliants you can tell the BIOS to not allocate an IRQ to the device which effectively disables it; the ML370 G2 uses an AIC-7899 chip on the motherboard. This problem also exists in the ~CentOS 4.3 base. SME 6.0 loads fine which would seem to indicate that the newer driver in ~CentOS 4.3 can't handle the older system (this Proliant is probably 5 years old). [[Bugzilla:373]]

===Older systems stop at reboot===
This may be an issue from the older P2 and early P3 era BIOS'es but the problem may also occur on some newer chipsets, that don't follow the "specs" for power saving features. Also, this problem seems to be more prevalent in multi-CPU machines. Only a kernel change could provide a real fix to this issue.

Try a different cd burner. We've found in the past that some drives provide an extra garbage block when reading back the image. This results in an incorrect md5sum value.

Most likely this is a problem with the video card or sound card. The best fixes are to replace the video/sound card, disable the video/sound in the bios (if it's integrated on the motherboard) or remove the video/sound card altogether. Video/sound isn't needed on the SME Server and can be managed via the server-manager.

Most likely, this is either a hardware or BIOS problem or a kernel bug. It's very unlikely we can fix any of those. However, you can try editing /etc/grub/grub.conf. In this file, close to the top, you'll see the latest kernel. It looks like this:

===Why is there a delay after verifying administrator password?===
On "slow" system, there is a delay (2-5 seconds) after verifying administrator password. This is because the password is actually set and checked at this point. Everything else we wait until the script is done to perform any actions.

This is intentional, since it required too much effort to keep it up-to-date as kernels change. The CD contains a rescue mode, which is a better environment for fixing problems, and a reinstall followed by a restore of the configuration works well without us supporting another method.

===4 disk install - md1 is raid1 and md2 is raid5===
Even if you have 4 (or more) disks, which are supported by your motherboard and ~CentOS, md1 is always set up as a 4 disk raid1. This is, because you can't boot off a raid-5. md1 is the boot partition and must either be non-raid or raid-1. md2 will be set up as a 4 disk raid5 as expected.
