This is a five node cluster, motherboards dual opteron from Supermicro . Storage uses the same motherboard as the five nodes, but with a 16 3,5 HD slots, with 12 occupied by WD enterprise disks . Storage runs Nas4Free . ( already try Freenas, same result ) Like I said, when I installed PVE 1.9 everything works fine for, now 9 days, and counting . In the five nodes, are embedded 2 network ports, connected to Linksys switcher, I am using it to serve the VMs . In one PCIe Slot there are an Intel 10 GB card, to talk with a Supermicro 10 GB switcher, exclusive to communication between the five nodes and the Storage . This switcher have no link with anything else . In the Storage, I use one of the embedded ports to manage, and all images are served through 10 GB card . After sometime, between 1 and 3 days the system is working, the nodes stops to talk with the storage . When it happens, the log shows lots of msg like this : Mar 6 17:15:29 nodo-01 pvestatd[2804]: WARNING: storage 'iudice01' is not online Mar 6 17:15:39 nodo-01 pvestatd[2804]: WARNING: storage 'iudice01' is not online Mar 6 17:15:49 nodo-01 pvestatd[2804]: WARNING: storage 'iudice01' is not online Mar 6 17:15:59 nodo-01 pvestatd[2804]: WARNING: storage 'iudice01' is not online Mar 6 17:16:09 nodo-01 pvestatd[2804]: WARNING: storage 'iudice01' is not online Mar 6 17:16:19 nodo-01 pvestatd[2804]: WARNING: storage 'iudice01' is not online Mar 6 17:16:29 nodo-01 pvestatd[2804]: WARNING: storage 'iudice01' is not online Mar 6 17:16:39 nodo-01 pvestatd[2804]: WARNING: storage 'iudice01' is not online Mar 6 17:16:49 nodo-01 pvestatd[2804]: WARNING: storage 'iudice01' is not online Mar 6 17:16:59 nodo-01 pvestatd[2804]: WARNING: storage 'iudice01' is not online After that, if I try to restart the pve daemon, it refuses to . If I try to reboot the server, it stops when the PVE daemon should stops, and stays there forever . The only way to reboot any of the nodes is a hard reset ! At first, I my suspects goes to Storage, changed from Freenas to Nas4Free, sane thing, desperation ! Then, for tests, I installed PVE 1.9 In all five nodes ( I have 2 systems running it for 3 years, so issue, this new system are to replace both ) Like I said, 9 days and counting !!! So, there is no problem in the hardware, and there is no problem with Nas4Free ! What left ?!? Fábio Rabelo
