The basic idea is to build a cheap & slow test bed for file & storage system scalability. Collectively, we have about 120TB (raw) of capacity to play with in one server. As we work through various issues, a couple of oddities popped out. The first is that udev grumbles during boot about "file name too long" like the following: Aug 17 06:49:58 megadeth udevd-event[20447]: unable to create db file '/dev/.udev/db/\x2fdevices\x2fpci0000:00\x2f0000:00:04.0\x2f0000:17:00.0\x2f0000:18:0a.0\x2f0000:1f:00.0\x2fhost11\x2fport-11:0\x2fexpander-11:0\x2fport-11:0:0\x2fexpander-11:1\x2fport-11:1:0\x2fexpander-11:2\x2fport-11:2:17\x2fexpander-11:3\x2fport-11:3:1\x2fend_device-11:3:1\x2fbsg\x2fend_device-11:3:1': File name too long The second is that the mpt2sas driver spews various messages like: Aug 17 06:55:17 megadeth kernel: mpt2sas0: log_info(0x31120102): originator(PL), code(0x12), sub_code(0x0102) Any insight into whether these are issues worth pursuing is appreciated, thanks!
