The problem isn't necessarily you, by the way. If those drives are accessible by more than one host, then you have no control what other hosts do. The SAN admin should zone the WWPNs and mask the LUNs to ensure that only the proper server has access to a specific LUN. The storage admin can help you determine if someone else is accessing the LUNs, whether from System z or elsewhere. (Hopefully you are using NPIV in all of your virtualization environments.) If you're getting errors on ECKD, then I suspect another LPAR is doing something to your disks. The fact that an OS has a different design point that your fave isn't unusual. You should see all the weird things z/OS does from my perspective. :-) But I think it's a credit to Linux that it *expects* hardware to be unreliable or interfered with, and it takes steps to protect you from it. Oh, and ext3 is way better than ext2 was. The fsck'ing (careful, there!) with ext2 would have driven you crazy. :-) Alan Altmark Senior Managing z/VM and Linux Consultant IBM System Lab Services and Training ibm.com/systems/services/labservices office: 607.429.3323 mobile; 607.321.7556 alan_altm...@us.ibm.com IBM Endicott ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 ---------------------------------------------------------------------- For more information on Linux on System z, visit http://wiki.linuxvm.org/
