We have a new toy to test very large& slow storage with built up from 5
SAS expansion shelves (Promise Vtrak J-Class) with 60 S-ATA drives and
16 SAS drives (the S-ATA drives each have a Promise Vtrak S-ATA MUX
adapter daughter card in the disk sled).
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
Ok, it looks like the way that udev handles it's internal "database"
can't handle paths that are larger than a single filename size.
Kay, I think this is all yours :)
thanks,

Happy to try patches, also happy to try and work around this with a different
configuration :-)
