Post subject: | R8.3 Recovery/Upgrade |
Last week I had the main os hard drive fail on my main backend. My current system is/was running Linhes R8.3, and I was planning on moving to R8.4.3 (latest at this time) prior to the failure. I do have access to R8.3 system backups that were saved on one of the the other storage drives. Thank goodness for Remote backups . My question is what is the best route to getting the backend up and running? Do I reinstall R8.3, restore a system backup, and then move to R8.4.3? Or Can I do a clean install of R8.4.3, and restore one of the system backups I have from R8.3? Thanks in advance. |

A clean R8.4.3 and restore should work. Just make sure to run mythtv-setup before restarting mythbackend after the restore as your DB schema will need to be updated. |

Thanks brfransen for the clarification. I totally forgot about running mythtv-setup after the restore. I will let you know how it goes. Thanks again. |

To close this thread off. Everything is back up an running. The database was restored successfully. The only issue I had was with add_storage.py. The system noticed the new drives but when i ran Code: sudo add_storage.py --no_destruction I was greeted with the error below.Code: Traceback (most recent call last): File "/usr/LH/bin/add_storage.py", line 1124, in <module> main(scan_only, destruction, no_mount, install_call, dir_sg) File "/usr/LH/bin/add_storage.py", line 656, in main disk_num = last_disk_num() File "/usr/LH/bin/add_storage.py", line 554, in last_disk_num return num_list[-1] IndexError: list index out of range Not a game ender. I was able to mount the drives manually, as i have done in the past, but using add_storage.py would have made things much easier/quicker. Doing a quick search I found a similar thread. The post states that the script has been corrected as of R8.4.1. This is more of a sanity check to make sure I didn't do anything incorrect. Thanks again brfransen. |

If you are running R8.4.3 that error can't be what was thrown because the line numbers don't match at all with the current add_storage.py. Did you maybe copy the error from the other thread? What is in /etc/storage.d? How exactly did you restore? Did you do any manual copies from the backup /etc to the new /etc? |

The error was copied from the referenced post. I will try to re-create the scenario when I am back home and post the correct/updated error (if any). As for what was restored. I did a database restore from the last backup I had before the dvr quit using the Health & Maintenance tab. |

I expect the error will be the same but the line numbers should be different. Nothing in /etc/storage.d should have been touched with the restore. I am curious to see what you have in /etc/storage.d. |
