Undelete ZFS file shared by Samba I've heard of people editing the disk to have ZFS use a previous state, but I don't know of a utility to do that. This would allow you to get to the files if they hadn't been over written. In addition, I've heard of some data carving tools that would be used on ZFS, mainly for forensics. |

Recommended technology for layered disk cache in linux @SpliFF: Just in case you hadn't seen this presentation on BTRFS. I thought it was interesting, but I have been out of the BTRFS loop for a while so there may be nothing new to you in the presentation. event.on24.com/eventRegistration/… |

Recommended technology for layered disk cache in linux @SpliFF: I'll have to check out btrfs, and bcache myself. I'm hoping for an arms race between ZFS and BTRFS, like of like Intel and AMD. With competition both sides are forced to innovate and the winners in the end are the users. |

Recommended technology for layered disk cache in linux I hadn't used it, but it appears ZFS is being ported to Linux. zfsonlinux.org If ZFS isn't the answer, I believe it soon will be. |

Recommended technology for layered disk cache in linux I only have a little experience with ZFS. In case you didn't now ZFS love lots of RAM (or L2ARC). I saw a video that said the default cache size is 80% of RAM (if that RAM isn't needed by something else), but that is tunable. Dedupe uses RAM so if you don't need hard drive space, you may want that RAM be used for caching. I linked to all seven videos on my blog scottmcclenning.blogspot.com/2010/10/zfs-cache-and-tuning.html If you want to learn about tuning ZFS, the videos and his blog should help. |

how-to: ZFS design and cache tuning : ARC, ZIL If you want a video series where they talk about how ZFS works and some tuning goto youtube.com/user/deirdresun and it is called "ZFS in the Trenches: Ben Rockwood at LISA 09" (7 in all). Ben talked about turning the cache and how to monitor ZFS. His blog is at cuddletech.com/blog I'm not sure that bug is still active, it isn't posted as fixed, but a workaround is posted in a related bug. When you go to that bug it was fixed in snv_56. Not sure if the second bug fix, fixed the first bug. I don't remember a reference to memory leakage in the video series. |

Tips on efficiently storing 25TB+ worth million files in filesystem After thinking about it, you’re right; DFS may be able to be used if you have a DFS root point to the folders living on other machines. That way the user would see one file structure and wouldn't need to know which machines the data actually lives on, DFS would know. That would work. Usually when I have people ask me about Windows DFS, they usually think it is a way to pool together storage space, and that is why I just to that conclusion. Sorry and your right that could work. |

Tips on efficiently storing 25TB+ worth million files in filesystem FYI: Windows DFS is a way to keep files/folders on multiple server in sync. It won't allow you to use the storage on multiple servers as a single storage drive. microsoft.com/windowsserversystem/dfs/default.mspx |
