- The four existing NFS servers are operating on equipment that is over 5 years old. Each of these servers hosts 32 GB of storage.
- wain025, the user/group disk, is routinely heavily loaded and not infrequently overloaded, sometimes leading to hangs and crashes.
- within the xroot cluster, the oldest four 32-GB servers are over 6 years old (wain017, 019, 020, 021)
- the 11 next oldest 32-GB xroot servers were purchased in 2009 (wain033, 034, 035, 036, 037, 038 and 039, 039, 053, 054, 055, and 056)
- six xroot servers have been made READ-ONLY by Wilko due to frequent problems (wain053, 054, 055, 056, 069, 071) This may be due to the extensive use of Seagate drives, which fail in a way that can hang the I/O bus. Note that Maintech has begun to use Hitachi drives for replacement.
