Problems with library located on a network drive
I've switched from a desktop PC to a notebook which resulted in migrating many of my files into NAS drives. That included Calibre library.
After a fresh Calibre install I was unable to add book or modify books in the library but I found the answer on the forum and followed that - deleted the metadata.db file and recreated library. There was some minor errors related to two books but in general that worked. Unfortunately I'm not able to add new books to the library - Calibre claims to have added some of them (not listing them in the error dialog) but it's not true. The most recent error that keeps appearing is lited below: Quote:
Of course I'm familiar with the official restriction related to placed Calibre library over networked drives (as stated here) but since I've been using sumbolic link to the library I was hoping to overcome potential problems (in many cases it helps). Apparently I wasn't right. Is anyone able to advise me on that? Last edited by mikolajek; 07-02-2014 at 07:38 AM. |

Use of network drives to store a Calibre library is not officially supported.
Some people seem to manage to get it to work, but others encounter issues. I am not sure if there are clear views of when one can expect it to work. |

But like you say, the Big Man himself says 'Not supported; on your own head be it!', so if the OP has issues with it, well, 'don't do that, then' Last edited by mbovenka; 07-02-2014 at 07:55 AM. |

Well, I have done a lot of "special" trying to cheat Calibre that its database is located on a local drive but I've apparently failed. The reason of my question was exactly what itimpi said - for some of forum member it somehow works. I wish I was one of them.
What I most likely do is copy my Calibre collection on a local drive and set up a sync mechanism to have an exact copy on my NAS server for security purposes. |

What type of network share are you using?
I'm going to assume Linux, which means you probably are using Samba? If that's the case make sure you check the Linux file system permissions AND Samba permissions. although this may not apply because you're probably using the standard NAS software. |

I had my calibre library on a NAS share for several years. I didn't have to do anything special, just moved the library and used it. I used NFS to share, no SMB or CIFS. Synology NAS and Ubuntu Linux on the PC. It worked fine, if a bit slow. Now I have the library on a bigger local drive, and backup to the NAS using BackInTime.
I assume that it is SMB and CIFS that causes problems. Last edited by Adoby; 07-13-2014 at 04:13 AM. |

It seems very hit-and-miss as to whether it will work for any combination of NAS and client and protocol. I think there are other factors such as your virus/internet security software and the setting you use that can come into play as well. |

Calibre running on just about any version of Windows seems to work fine using a samba share over an nfs file system. Linux clients will not work unless you disable oplocks on mounting the share. I think the option is something like --nobrl but you will need to check this. No matter what OS you use, it is also very important to make sure your share is not accessed simultaneously by more then one machine, as this can lead to corruption.
Remember, Kovid does not recommend or support this for a reason. Use this at your own responsibility. |
