hello,
some extended maintenance is currently taking place on the NFS server
for /home, so hemlock is offline. this shouldn't take more than a few
hours. i'll post a full explanation when it's finished.

the maintenance is finished now. the problem was caused by filesystem
corruption on clematis:/aux0, the QFS filesystem where hemlock's /home
is currently mounted from, when the connection to the iSCSI array was
broken. i have replaced this filesystem with a VxFS filesystem, which
should be more resiliant against problems like this.
the iSCSI problem was my fault, so sorry for that. to prevent it
happening in the future, i've asked for the array to be connected
directly to clematis's NIC, which should be more reliable. in the
longer term the plan is to move hemlock's /home back to a local array;
this should happen either this month or next, when a new array is
installed at knams.
a very small number of files were unrecoverable from the damaged /home.
if any of your files are missing, mail ts-admins or file a bug and they
can be restored from a backup.
