PNWDweller Posted February 7, 2015 Share Posted February 7, 2015 Is there a way to convert a UFS drive to EXT4 without losing the data? The reason I ask....is a tl;dr so only if you are curious. I have been running NAS4Free for the last year or so with no issues. The other day, I got the irresistible bug to take the PC I was using for the NAS and beef it up by replacing the software by rolling my own server using Owncloud (so I can have my own personal Dropbox type of clone), adding a DLNA server to serve my music to my home theater as well as other server things. Anyway, back on topic... All of my files and data are stored on a 1TB drive formatted in UFS format. On this drive, I actually have only used about 400GB of space on the drive. I quickly realized that while it is not built in, Centos 7 does not support mounting UFS formatted drives out of the box, but can be done by doing some kernel compiling which I really do not wish to do at this point. I figured it would be easier to go ahead an copy the files off of the UFS drive back in from NAS4Free to an EXT2 formatted drive I have. I pulled out my 500GB USB 3 external drive which has the EXT2 format and I went ahead and started the extremely sloooow copy of each file by file to the drive. My computer only has USB 2 which bottlenecked it some. So, I watched the transfer process go through and then to my surprise, I ran out of room on the 500GB USB drive. Even though, after several GB's reserved for system, I should have had enough space. So my copy never finished. A lightbulb popped into my head today to go and Clonezilla the UFS partition to my 500GB drive which I did. I then formatted the UFS drive to EXT4 and went about my way to restore the Image I created and quickly learned that OOPS! Clonezilla (at least in the default modes), also reformatted the drive once again to the UFS format. So I am back to square 1.

PNWDweller Posted February 7, 2015 Author Share Posted February 7, 2015 IIRC - I did try the command: mount -r -t ufs -o ufstype=ufs2 /dev/sdb1 /home/admin/ufs_mount in CentOS 7 and it did not work. I am in the process of restoring the UFS right now from the Clonezilla, so I will try again after that (02:13:05 remaining). I know Ubuntu does support UFS out of the box, but I am more well versed in Centos.
