Hi. I'm trying to list all of the GFS limits that I can find. The one I'm most interested in is max filesystem size. Here are the ones I've found so far. Is the theoretical limit on filesystem size 2^64 bytes or is there a practical constraint? I couldn't find that. filesystem size: ? file size: gfs_dinode has u64 di_size member, so 16777216 TB is theoretical max file size block size: gfs_mkfs manpage says min block size 512 bytes, max block size is the page size for the host Also, according to a comment at the top of gfs_ondisk.h, the de_rec_len member of gfs_dirent limits the FS block size to 64KB. jounal size: gfs_mkfs manpage says min is 32MB extended attributes: max name length: 255 bytes max data length: 65535 bytes -- Ed L Cashin <ecashin@xxxxxxxxxx>
