Workaround for inotify on NFS-clients

I run multiple virtual machines which shares all their data via a NFS-server. I have an application that fetches files, and another server that watches for new files in a folder, using inotify. But i quickly noticed that inotify does not work over NFS. I “fixed” this by doing a simle workaround that finds all files in the watched folder, and simply touches them. This causes inotify to dectect those files.

find s -type f -exec touch {} \;

This works for me since i can simply run the command via cron, or via another scheduled job, but that does not mean that i works for your case. But perhaps it gives you some ideas.


Time used to convert a TB sized ext3 filesystem to btrfs

I have expanded my 11×1.5TB RAID6 to 10X3TB, and since i have everything in one ext3-filsystem, i realised that ext3 simply do not support such filesystem sizes yet. Or to be correct, the filesystem supports it but it is still not possible to resize a filsystem on Ubuntu above 16TB.

I could only find to solution which did not force me to drop all data, and that was to convert it to btrfs, as it support a convertion. I did not time the whole process but it did take me less than 30 hours for 9.5 TB.
