We never used NetApp because even the physical machines were crap. Terrible performance and reliability and super high cost. We had to abandon them because they would fail under load. Not cut out for storage duties.

Bit of a necro post, but I'm finally getting back around to NFS review for RHCSA. nfsstat -s tells me I'm using version 4.

@scottalanmiller Sounds solid. The speed difference is dramatic. Thanks.

rpcbind services is not required for NFSv4

AID 10 on Linux File Server machine, how can I speed up this NFS storage by an intelligent
cache, for example I wish to add another 250 GB SSD to act as cache, how will tha

Yeah the RAID 10 is on HDD, due to cost effectiveness. Will check LVM since its baked in.

@phlipelder said in Use Hyper-V to replicate Linux vm file share:

Hyper-V Replica would work in this situation with a few caveats.

There is a 15 second limit on replication cycles. If the VMs are running database/active services this could be a problem.

That would be handled earlier in the process by the backup job. If the backup is good, the replication won't cause an issue. If the backup is bad, the replication can't fix it, of course, but will replicate the bad backup. But the only place that this can be addressed is in the backup step, the replication is of backup files, so not at a point in the process where it matters.

"Garbage in garbage out" never seems to go away. It's been the bane of our existence since the switch to image/block based backups. :S

File backups suffered from this, too. Databases are just hard to back up.

HW is simple:

2x SSD for o/s 4 - xx SSD for NFS shares

Why would you have drives for the OS? This both breaks standard storage practices AND assumes a physical install which is a 'no no'.

Why would you assume a physical install ?
I'm installing the hypervisor (in this case FC28) on a Raid1 array of 2x SSDs

Because you stated a dedicated array for the OS, not for the hypervisor. I'm only going by what you wrote. If you wanted dedicated for the OS, you'd need it whether you had a hypervisor or not.

Understood. Next time, will be more specific

Since that's a lot of money to spend just for a hypervisor that isn't used, it seems much more rational to use it for an OS than a hypervisor. It's not that there is truly zero value to a dedicated HV array, but it is nearly zero. SSDs, even cheap consumer ones, aren't free. But the value is so low, they'd basically have to be.

Maybe problem with noowners mount option?

@poorizad said in Storing Elastix 2 Call Recordings on NFS NAS Share:

@scottalanmiller hi again....i guess the nfs drive is unmount from the server, because no file record on Nas after the 2016/07/28.....nothing changed on settings.....but a few server shutdown for hardware maintenance.....how can i fix it again ?

Try the mount command again. It might mount right up. If the NFS server has restarted, it would disconnect.

Bug found, scheduled for release in 4.15

No, there is nothing like that. The filesystem is just not there. It would warn you, though, so you would know not to be trying to save to something that doesn't exist.
