Huge file systems on Linux (Experienced Admin Please)
My company just had a terriable experience with an XFS file system with more than 13 TB of data. I need the advise of the most experienced Admins, which file system should I use? We probably will have to recreate the filesystem so it is time to find the options, pros and cons.

Problem with XFS: It was unstable and got corrupted. Moreover, we tried to recover it but it did not. Initially it was not even showing the file system. When e.g. I did ls -l and it would show question marks. Then we tried to run file system repair command and it stopped every time in the middle with segmentation fault. We just lost confidence on XFS and wanted a stable and recoverable and stable filesystem.

Reason for a large filesystem: The server is used for backups and also for transfer of backups. I am new in the organization and there is little in my control. It appears that they have NetApps which has snapshots. This system takes local backups--it is located in the same data center as the NetApps and other source computers. Then the data is moved to another location -- remote backup. That is done through this computer too. Things are not done the ideal way and so is the situation with most organizations that I have consulted with. But I want to learn the correct ways and strive to work on ideal practices that is why I pick brains of experts like all of you. I really appreciate participation of all of you!!
go with solaris and ZFS INSTEAD

Thank you all, seniors. I appreciate everyone's help. There may be small difference of opinions but you were all trying to help me and I am grateful for that.

Read/Write ratio is almost equal. We are creating backups in and out of this filesystem so the ratios are equal.
