Just for the record, mounting with cifs didn't work either. /proc/mounts
did not show the xattrs option in either case. So I'm guessing that
xattrs on a remote cifs is just not supported yet, although I'm not
quite certain what is missing. The kernel appears to have xattr enabled:
# grep -i attr /boot/config-2.6.18-128.2.1.el5
CONFIG_RAID_ATTRS=m
CONFIG_SCSI_SPI_ATTRS=m
CONFIG_SCSI_FC_ATTRS=m
CONFIG_SCSI_ISCSI_ATTRS=m
CONFIG_SCSI_SAS_ATTRS=m
CONFIG_EXT2_FS_XATTR=y
CONFIG_EXT3_FS_XATTR=y
CONFIG_EXT4DEV_FS_XATTR=y
# CONFIG_JFFS2_FS_XATTR is not set
CONFIG_CIFS_XATTR=y
Anyone know why xattrs on a (mounted) remote fs (nfs and/or cifs)
wouldn't work? I think the code for NFS isn't in the COS5 kernel, but I
really expected cifs would work.
Anyhow, I just rsync'd w/ --xattr over ssh and that worked fine.
Moving on. :)
