Hi, Some of our data servers have two disks and I am using the oss.cache directive to use both disks to support a single namespace. However, it looks like the users of our applications have already run into a problem. All of the files are stored in one directory (for a single cache) and the filename is the full namespace path with "/" substituted with "%". Our problem arises from the fact that full namespace path is now limited to the leafname length of the filesystem (255 characters) when writing to the cache directory. I see a couple of ways to mediate the problem; removing one disk or using and LVM to create one drive in the OS. I am curious if there are other alternatives? If I have to move to one disk, I would like to migrate the data in the existing caches to other data servers while I rework the existing system. What is the best way to migrate this data? I am planning on taking the "problem" data server off-line and use xrdcp to move the data to the other servers. Regards, Patrick
