ReadyNAS NV+ syslogd taking 100% CPU
Hi - I've got a Sparc-based ReadyNAS NV+ that I've had for years. Currently running RAIDiator 4.1.14; 4 x 2TB drives in Raid-X configuration, with about 300G/5.5T free. Lately, the NAS box will become non-responsive during transfers and I have to pull the power, and re-install the OS in order to make it happy. Unfortunately, it's not happy for more than a few hours at a time lately, and I've had to do this once a day or so. By non-responsive, I mean that I can ping it, but not telnet/ssh/frontview, and the front-panel power-button seems to do nothing with a brief press. I've bought its replacement, and am transferring ~ 6TB off it via CIFS, and it is still locking up. This last time, I left top running in a terminal window, which was still updating, though slowly. top - 18:24:58 up 1 day, 1:18, 1 user, load average: 9.04, 9.07, 9.02 Tasks: 67 total, 5 running, 62 sleeping, 0 stopped, 0 zombie Cpu(s): 1.6% us, 98.4% sy, 0.0% ni, 0.0% id, 0.0% wa, 0.0% hi, 0.0% si Mem: 226352k total, 221632k used, 4720k free, 8976k buffers Swap: 767904k total, 1856k used, 766048k free, 188352k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1571 root 25 0 2128 960 800 R 97.7 0.4 1000:39 syslogd 1066 root 16 0 2992 1168 896 R 2.3 0.5 33:38.83 top 1 root 15 0 2000 592 496 S 0.0 0.3 0:05.09 init 2 root 34 19 0 0 0 S 0.0 0.0 0:00.03 ksoftirqd/0 3 root 10 -5 0 0 0 S 0.0 0.0 0:00.04 events/0 4 root 10 -5 0 0 0 D 0.0 0.0 0:00.03 khelper 5 root 10 -5 0 0 0 S 0.0 0.0 0:00.01 kthread 10 root 10 -5 0 0 0 S 0.0 0.0 0:09.36 kblockd/0 13 root 10 -5 0 0 0 S 0.0 0.0 0:00.01 khubd Syslogd with 1000 minutes of runtime, and 98.4% sys CPU seems very likely to be the cause of my problem. The rootfs wasn't full just prior to the CIFS transfer. nasgul:~# df / -i Filesystem Inodes IUsed IFree IUse% Mounted on /dev/hdi1 128000 11330 116670 9% / nasgul:~# df / -h Filesystem Size Used Avail Use% Mounted on /dev/hdi1 1.9G 642M 1.3G 33% / So, what's my next step here? A factory reset would be more palatable after I'm convinced that my data has been successfully backed up to the new NAS box. What can I do to keep the box up while I do my transfers and verifications? Thanks.
