This was previously posed to the sun-managers mailing list but the only reply I received recommended I post here at well. We have a production Solaris 10u5 / ZFS X4500 file server which is reporting NLM_DENIED_NOLOCKS immediately for any nfs locking request. The lockd does not appear to be busy so is it possible we have hit some sort of limit on the number of files that can be locked? Are there

While I understand everything at Oracle is "top secret" these days. Does anyone have any insight into a next-gen X4500 / X4540? Does some other Oracle / Sun partner make a comparable system that is fully supported by Oracle / Sun? http://www.oracle.com/us/products/servers-storage/servers/previous-products/index.html What do X4500 / X4540 owners use if they''d like more

The vendor wanted to come in and replace an HDD in the 2nd X4500, as it was "constantly busy", and since our x4500 has always died miserably in the past when a HDD dies, they wanted to replace it before the HDD actually died. The usual was done, HDD replaced, resilvering started and ran for about 50 minutes. Then the system hung, same as always, all ZFS related commands would just

Greetings, on this matter, Sunfire x4150 a 1U machine with 2xcpu sockets, "eight" drive bays, 64 GB expandability, 4 NIC packs quite a punch for its size. I don't think I've ever seen such power in such a small package Regards Rajagopal

Anyone here using http://www.sonnettech.com/product/tempossd.html with a zfs-capable OS? Is e.g. OpenIndiana supported? Thanks.

I''ve recently upgraded my x4500 to Nevada build 97, and am having problems with the iscsi target. Background: this box is used to serve NFS underlying a VMware ESX environment (zfs filesystem-type datasets) and presents iSCSI targets (zfs zvol datasets) for a Windows host and to act as zoneroots for Solaris 10 hosts. For optimal random-read performance, I''ve configured a single

Hi guys, we are proposing a customer a couple of X4500 (24 Tb) used as NAS (i.e. NFS server). Both server will contain the same files and should be accessed by different clients at the same time (i.e. they should be both active) So we need to guarantee that both x4500 contain the same files: We could simply copy the contents on both x4500 , which is an option because the "new

IHAC Who has an x4500(x86 box) who has a zfs root filesystem. They installed patches today, the latest solaris 10 x86 recommended patch cluster and the patching seemed to complete successfully. Then when they tried to reboot the box the machine would not boot? They get the following error NOTICE: spa_import_rootpool: error 5, Inc. All rights reserved. Cannot mount root on /pci at

I am bumping this thread because I too have the same question ... can I put modern 3TB disks (hitachi deskstars) into an old x4500 ? If not, would the x4540 accept them ? -- This message posted from opensolaris.org

Hello, How do you tell how much of your l2arc is populated? I''ve been looking for a while now, can''t seem to find it. Must be easy, as this blog entry shows it over time: http://blogs.sun.com/brendan/entry/l2arc_screenshots And follow up, can you tell how much of each data set is in the arc or l2arc? -- This message posted from opensolaris.org

Since ZFS already has error correction, would drives that limit the time a hard drive attempts to recover from errors such as WD RE drives or Seagate ES drive be necessary? Would it be safe to use standard hard drives without the Time Limited Error Recovery feature in a RAIDZ array? This message posted from opensolaris.org

After applying 125205-07 on two X4500 machines running Sol10U4 and removing "set sata:sata_func_enable = 0x5" from /etc/system to re-enable NCQ, I am again observing drive disconnect error messages. This in spite of the patch description which claims multiple fixes in this area: 6587133 repeated DMA command timeouts and device resets on x4500 6538627 x4500 message logs contain multiple

Hi, I''ve ordered a new server with: - 4x600GB Toshiba 10K SAS2 Disks - 2x100GB OCZ DENEVA 2R SYNC eMLC SATA (no expander so I hope no SAS/ SATA problems). Specs: http://www.oczenterprise.com/ssd-products/deneva-2-r-sata-6g-2.5-emlc.html I want to use the 2 OCZ SSDs as mirrored intent log devices, but as the intent log needs quite a small amount of the disks (10GB?), I was wondering

Hi all I ran a workload that reads & writes within 10 files each file is 256M, ie, (10 * 256M = 2.5GB total Dataset Size). I have set the ARC max size to 1 GB on etc/system file In the worse case, let us assume that the whole dataset is hot, meaning my workingset size= 2.5GB My SSD flash size = 8GB and being used for L2ARC No slog is used in the pool My File system record size = 8K ,

Before I open a new case with Sun, I am wondering if anyone has seen this kernel panic before? It happened on an X4500 running Sol10U3 while it was receiving incremental snapshot updates. Thanks.

Heya all, I''m working on testing ZFS with NFS, and I could use some guidance - read speeds are a bit less than I expected. Over a gig-e line, we''re seeing ~30 MB/s reads on average - doesn''t seem to matter if we''re doing large numbers of small files or small numbers of large files, the speed seems to top out there. We''ve disabled pre-fetching, which

I''m running a mirrored pair of 2 TB SATA drives as my data storage drives on my home workstation, a Core i7-based machine with 10 GB of RAM. I recently added a sandforce-based 60 GB SSD (OCZ Vertex 2, NOT the pro version) as an L2ARC to the single mirrored pair. I''m running B134, with ZFS pool version 22, with dedup enabled. If I understand correctly, the dedup table should be in

I look after an x4500 for a client and wee keep getting drives marked as degraded with just over 20 checksum errors. Most of these errors appear to be driver or hardware related and thier frequency increases during a resilver, which can lead to a death spiral. The increase in errors within a vdev during a resilver (I recently had three drives in an 8 drive raidz vdev "degraded")
