Version 4 (brfransen, 04/28/2013 10:53 am)
| 1 | 4 | brfransen | h1. Upgrading LinHES R7.X to R8 |
|---|---|---|---|
| 2 | 1 | ||
| 3 | 1 | LinHES R8 contains some fairly significant underlying changes. |
|
| 4 | 1 | One of these is the partition layout change which makes a direct in place upgrade from previous versions impossible. |
|
| 5 | 1 | However with a little bit of data moving it's possible to update to an R8 install with minimal effort. |
|
| 6 | 1 | ||
| 7 | 1 | h2. *Please read through all the steps before proceeding.* |
|
| 8 | 1 | ||
| 9 | 1 | Before starting the update, a decision must be made on where to install R8. Either a new hard drive may be used or the existing hard drive for R7. |
|
| 10 | 1 | If the drive for R7 is used, then all of /myth, the database and anything else you need should be backed up. |
|
| 11 | 1 | *Because it is a destructive process using a new hard drive is recommended.* |
|
| 12 | 1 | ||
| 13 | 1 | h3. Backup R7 system |
|
| 14 | 1 | ||
| 15 | 1 | On the R7 system create a system backup and copy it to another machine. |
|
| 16 | 4 | brfransen | To create the backup run: sudo lh_system_backup_job |
| 17 | 1 | This will create a file in /myth/system_backups/ named backup.$todays_date. |
|
| 18 | 1 | Next copy the most recent backup file to another machine, preferably one with a web browser that can be used later. |
|
| 19 | 1 | If you are reusing a R7 hard drive then all of /myth will need to be copied to another machine. |
|
| 20 | 1 | ||
| 21 | 1 | h3. Install R8 |
|
| 22 | 1 | ||
| 23 | 1 | Perform a new install of R8, using the same hostname that R7 used. |
|
| 24 | 1 | Only the hostname needs to match, the ip address may be different if needed. |
|
| 25 | 1 | *Before doing the install it's recommended to disconnect any additional data drives that may be in the system.* |
|
| 26 | 1 | ||
| 27 | 1 | h3. First setup for R8. |
|
| 28 | 1 | ||
| 29 | 1 | First setup can be skipped, because the data for this step will be restored in the next step. |
|
| 30 | 1 | ||
| 31 | 1 | h3. Restore R7 database into R8 system |
|
| 32 | 1 | ||
| 33 | 1 | Using a web browser open HTTP://$ip_of_r8_machine. |
|
| 34 | 1 | Navigate to system->system health |
|
| 35 | 1 | On this page you should see “primary server” centered in the screen. |
|
| 36 | 1 | Two lines below that will be the hostname of the system just installed. |
|
| 37 | 1 | The name of the system should be underlined indicating it's a link. |
|
| 38 | 1 | *If this page doesn't exist wait up to 10 minutes for the link to be created.* |
|
| 39 | 1 | ||
| 40 | 1 | Once the link is created, click on hostname to open the operations page for the master backend. |
|
| 41 | 1 | ||
| 42 | 1 | Upload the system backup file from the R7 machine using the “upload file to restore” option on the web page. |
|
| 43 | 1 | ||
| 44 | 1 | After upload is complete, go back to the main operations page and select “Restore database” |
|
| 45 | 1 | Check partial restore, and finally select the file to restore from the drop down list. |
|
| 46 | 1 | Press the GO button to start the restore. |
|
| 47 | 1 | This is using very basic HTML, so the page may appear to stall while it's working. |
|
| 48 | 1 | Just wait it out and it will eventually come back in a few minutes. |
|
| 49 | 1 | ||
| 50 | 1 | *After it's done, reboot the machine and validate that the data was restored and the list of videos and recordings was uploaded properly.* |
|
| 51 | 2 | brfransen | *If the master backend is not available, open mythtv-setup (ctrl+s) and check the value of master_backend_ip * |
| 52 | 2 | brfransen | *Also the backend will not complete startup if certain tuners are defined but not available. For instance the Ceton InfinitTV tuners* |
| 53 | 1 | ||
| 54 | 1 | h3. Copy Media files onto the R8 system |
|
| 55 | 1 | ||
| 56 | 1 | With R8 the location for data has changed to /data/storage/$drive_serial_number. |
|
| 57 | 1 | For convenience a symlink of /myth → /data/storage/$drive_serial_number/media has been provided. |
|
| 58 | 1 | ||
| 59 | 1 | h3. Add additional drives |
|
| 60 | 1 | ||
| 61 | 1 | The last step is to add back any additional media drives that were part of the R7 system. |
|
| 62 | 1 | Adding them can be done two different ways. |
|
| 63 | 3 | brfransen | a) add them with the command: add_storage.py --no_destruction |
| 64 | 1 | This will add the drives in an automated fashion and follow the R8 layout. |
|
| 65 | 1 | *The drives will NOT be formatted or partitioned.* |
|
| 66 | 1 | *The drives will be available for auto-sharing and added to storage groups.* |
|
| 67 | 1 | ||
| 68 | 1 | b) The drives may also be added manually without using add_storage. |
|
| 69 | 1 | The steps for doing this are the same as they were in R7. |
|
| 70 | 1 | As long as the drive is mounted at start up add_storage will ignore any drive that is added manually. |
|
| 71 | 1 | ||
| 72 | 1 | ||
| 73 | 1 | ||
| 74 | 1 | At this point all the media and settings should be migrated over. |
