Again, no real problems
On the system front, nothing weird – once more no weird results in email:

but on 1st, 6th and 7th of July, logs on relay attempts used 800 blocks on disk but it seems EOF was < 4 blocks - so the files were deleted. On the hardware front however, changes have been made. Mid July, I found that one of the RAID disks in Diana was bad, which may have contributed to performance issues. It also made a lot of noise I found the right type (MAW300NP: 300 Gb, 10K rpm U320 SCSI with 64-bit connector) via Internet, but in the UK, I ordered 2 and had to pay taxes on import....; placed one in Diana and found that the old 9GB SCSI-2 disk didn't work either so that one was removed as well. Plus that the cause of the bad cooling was found tobe cause by accumulated dust in front. Cleaned that, and after that, Diana was put back into action and is running ever since. During that time without disks, I used Dione - the second DS10 - as a backup for all activities except email because I could not handle mail that was on Diane. Dione could be started as well, even using the (assumed broken) cache memory; found that the batteries are bad so caching is now disabled. After the system had hung - again - and was restarted, I managed to make a backup of all four logical disks, hoping it didn't hang again. But it didn't, and Dione was kept alive for one more day, until Diana was re-activated - now with a new RAID disk and a cleaned front so the fans don't have to run at high speed anymore - CPU temp is now well below 40, without extra help. The last few says we have been plagued by power outages, some less than a minute, one for several hours. But since I do no longer have 7 disks that need to spin up - causing a power surge causing loss of power in the attic - there is no need to gradually startup the systems up here. Some outages - in the night - went unnoticed as long as you didn't look at the date and time of operator logs...
