If the disk does fail and isn't redundant, lots of things will break. For this same reason, swap should be on redundant disk as well. Also, the AFS cache will be cached the same as the local filesystem in RAM. Hopefully most reads will come from RAM and not from disk. <<CDC _______________________________________________ HCoop-SysAdmin mailing list [email protected] http://hcoop.net/cgi-bin/mailman/listinfo/hcoop-sysadmin
