I recently updated my mac pro from Mavericks to Yosemite. Afterwords my ZFS raid 5 stopped working (was not seen by the system). Please read this entire guide and the warnings before trying to fix your issue! Also please backup your data before trying to fix your zfs raid.
To fix this I did the following:
Downloaded ZFS 1.2.7 from HERE
Next i upgraded my zpool from Terminal
zpool upgrade data (NOTE: data is the name of my zpool change this to your zpool’s name.)
After all this i noticed the mount point for my zpool was not set so i set the mount point.
zfs set mountpoint=/Volumes/data data
To verify the above command worked i displayed the mount points
After this i saw that it was not mounted so to mount the pool you do
After this I was able to use my raid 5 drive.

Well as the title says I had been getting an internal-server-error-500/ error when uploading files via WordPress. I also had these error in my other non-wordpress sites like my MediaWiki. I use ISPconfig to host everything so I went down a rabbit hole to fix this. I saw several guide / suggestions on the issue and no single guide worked for me so below is a list of the steps I took to fix the issue.
Its worth noting this was a combination of ISPconfig and PHP that was causing the error and thats why most of the single guides to fix it did not work for me.
As normal follow this at your own risk and it helps if you have linux experience to tailor these to fit your system.
1) First under ISPconfig I added the following settings in the custom PHP setting section of each website having issuesdisplay_errors = On
post_max_size = 50M
upload_max_filesize = 50M
2) ssh to your server and edit the php.ini file located in: /etc/php5/cgi
change the upload_max_filesize = 2M from 2M to 50M
also change post_max_size = 2M to 50M
exit and save file
3) Last edit fcgid config file
add the line MaxRequestLen 52428800
Save and exit
I added this line under FcgidConnectTimeout 20 this is what mine looks like
AddHandler fcgid-script .fcgi
4) restart server and wallah you can now upload any image that is 50mb or less!
