Hi. The problem still exists for me, I haven't been able to get equipment yet, but the data is still sitting on a bunch of hard drives. On Sun, Jan 17, 2016 at 8:18 PM, Launchpad Bug Tracker < 1345...@bugs.launchpad.net> wrote: > [Expired for e2fsprogs (Ubuntu) because there has been no activity

To jump in for Ted here; I'm pretty sure that "very large" is in the millions range. Whatever the cause though, the best way for us to be able to reproduce, diagnose, and fix it is with an image of the filesystem, even if it is with the file names scrambled ( the names don't really matter anyhow,

Hi. I checked into another server that is waiting to upgrade >16TB pending this issue get resolved. Can you provide more information as to the statement "very large number of hard link". This other system has approx 150K hardlinks and growing daily. I'm not sure if we are talking about millions or

the nature of the content is confidential so I wouldnt' be able to get you an e2image of the file system. it has live data. I am guessing that it is possibly the high number of files or the nature of the file system corruption. I know that the fsck was not clean, and it just keeps sucking up

You do realize that e2image doesn't contain any data blocks --- just file system metadata blocks, right? And if you are concerned about the directory names being too revealing, e2image has a -s option which will scramble the directory file names. See the section "RAW IMAGE FILES" in the e2image

I am not familiar with the tool, but I was concerned about the file/directory names. I can look into the -s option and might be doable. I am still without a working chassis that can handle as many harddrives I have. I have a new motherboard and card. I was able to find online other people having

There are plenty of people who *are* able to check file systems larger than 16TB. So talking about it in terms "that problem" doesn't make much sense.

FYI. There was about 15TB (back when I initially ran into the problem, maybe about 11-14TB) of hardlinks. The Hardlinks are used so that rsync can handle directory name changes and not have to copy the whole directory over again. Thus each file would have a hardlink. I estimate maybe 40K+ or 80K+

As of 1 month ago I was still having the problem. The chassis last month has failed and i don't have another chassis that can handle that many drives. I am on hold until I can get funding to get another chassis. I have moved to 6TB drives for another setup, but I limited the partition to 16TB

I just tried a fresh install of 14.04.2 in a vm with a 20 tb virtual disk and fsck seemed to work fine. It might be specific to your disk contents. If you can reproduce this, please capture an image of the filesystem metadata with e2image -r ( and bzip2 that ) and attach it and I can try running
