extN xattrs are fairly limited, because iirc all xattrs of a given inode must be stored in the same block. I don't think XFS has any serious limitations (count/size) for them, but the Linux kernel itself limits the size to 64K.
- ape4 8y agoYou are correct. "man 5 attr" says: In the current ext2, ext3, and ext4 filesystem implementations, the total bytes used by the names and values of all of a file's extended attributes must fit in a single filesystem block (1024, 2048 or 4096 bytes, depending on the block size specified when the filesystem was created).
- user5994461 8y agoI would assume the block size is at least 4k for anything created in this era.
