Hi David, Thanks for your reply. > Hmm, so this "async" (sync=disabled?) ZFS tunable means that it > completely ignores O_SYNC and O_DIRECT and runs the entire workload in > RAM? I know nothing about ZFS, but that sounds like a mighty dangerous > setting for production deployments. Yes, you are correct - sync writes will flush to RAM, just like async, will stay in RAM for

Hi, I have a ZFS dataset that has sync writes disabled (setting sync=disabled) which means that it will only do async writes, and sync requests get converted to async writes. The ZFS dataset is hosted on a single Samsung 840 Pro 512GB SATA SSD. I have this same dataset served as a Samba share, using Proxmox VE 6. Samba version 4.9.5-Debian (Buster), protocol SMB3_11. Kernel version 5.0.15. To

hi guys I wonder if any of you might be using SFN6122F-R7 SFP+ (SFC9000, same firmware everywhere, Centos 7.5 too. I'm trying poor man's setup to get the servers onto 10GbE network. Setup is such that three Dell R815 are connected to each other, each has one Solarflare(SFP ports) and each Solarflare is set as net-team(both ports on a card are net-team device) with runner in broadcast

Hi Jeremy, Here's the log with log level 10: https://pastebin.com/0EAuz2B8 The location of the shared folder: /pool/shadowtest The location of the snapshots: /pool/shadowtest/.zfs/snapshot Here are how snapshots are named: autosnap_2019-09-01_13:29:01_daily autosnap_2019-09-01_13:29:01_hourly autosnap_2019-09-01_13:44:09_frequently And this is currently in my smb.conf file: [shadowtest]

hi, I have a hard time figuring this out, the kernel says: ... ix0: <Intel(R) PRO/10GbE PCI-Express Network Driver, Version - 2.5.15> port 0xecc0-0xecdf mem 0xd9e80000-0xd9efffff,0xd9ff8000-0xd9ffbfff irq 40 at device 0.0 on pci4 ix0: Using MSIX interrupts with 9 vectors ix0: Ethernet address: 90:e2:ba:29:c0:54 ix0: PCI Express Bus: Speed 5.0GT/s Width x8 ix1: <Intel(R) PRO/10GbE

From: Tonghao Zhang <xiangxia.m.yue at gmail.com> This patch improves the guest receive performance from host. On the handle_tx side, we poll the sock receive queue at the same time. handle_rx do that in the same way. For avoiding deadlock, change the code to lock the vq one by one and use the VHOST_NET_VQ_XX as a subclass for mutex_lock_nested. With the patch, qemu can set differently the
