you will.. even if the SAN is perfect, you will hit bugs in the filesystem code.. from lots of rsync hard links or like this one from raidtools last week: Feb 9 05:38:39 orbit kernel: mptbase: ioc2: IOCStatus(0x0043): SCSI Device Not There Feb 9 05:38:39 orbit kernel: md: write_disk_sb failed for device sdp1 Feb 9 05:38:39 orbit kernel: md: errors occurred during superblock update, repeating Feb 9 05:39:01 orbit kernel: raid6: Disk failure on sdp1, disabling device.
