Hi All, Is there a way to tune the zfs prefetch on a per pool basis? I have a customer that is seeing slow performance on a pool the contains multiple tablespaces from an Oracle database, looking at the LUNs associated to that pool they are constantly at 80% - 100% busy. Looking at the output from arcstat for the miss % on data, prefetch and metadata we are getting around 5 - 10 % on data,

Hi, we had a server that lost connection to fiber attached disk array where data luns were housed, due to 3510 power fault. After connection restored alot of the zpool status had these permanent errors listed as per below. I check the files in question and as far as I could see they were present and ok. I ran a zpool scrub against other zpools and they came back with no errors and the list of

Hi, I am wondering if there is a guideline on how to configure ZFS on a server with Oracle database? We are experiencing some slowness on writes to ZFS filesystem. It take about 530ms to write a 2k data. We are running Solaris 10 u5 127127-11 and the back-end storage is a RAID5 EMC EMX. This is a small database with about 18gb storage allocated. Is there a tunable parameters that we can apply to

I decided to post this question to the mailing list because it needs ZFS knowledge to be solved. The situation is like this: I have a blade server that boots from a LUN, which has no additional storage or internal disk but that LUN used to boot. MPxIO works perfectly; but the management wants to use EMC PowerPath, because the company already has an investment on licensing. After disabling

Hi Folks.. We have started to convert our Veritas clustered systems over to ZFS root to take advantage of the extreme simplification of using Live Upgrade. Moving the data of these systems off VxVM and VxFS is not in scope for reasons to numerous to go into.. One thing my customers noticed immediately was a reduction in "free" memory as reported by ''top''. By way

As is altogether far too common an occurance, we were having a problem where a file was not inheriting the correct ACL, but rather a horribly munged one resulting in incorrect permissions and security problems. It appeared something was chmod''ing the file after creation, but despite best efforts we simply could not find the culprit. After much investigation, we determined the ACL was

Hello list, What''s the current production-readiness of OI 151a? I''m evaluating Solaris 11 at the moment on HP server hardware + SAS JBODs. Also considering picking up a Thumper/Thor on the used market. For a ZFS storage server, is it a better idea to just stick w/ Oracle Solaris, or is OI also a good bet? How do the ZFS implementations differ between Solaris 11 and OI? Thanks

Hi All, We are currently in the process of testing Solaris 10 with ZFS and Oracle and are running it on a T2000. When checking performance statistics on the T2000, we notice that only one thread of the CPU appears to be doing any of the processing. Leaving all other threads seemingly idle. Are there any tuning parameters that need to be set or changed when running Oracle on T2000 using

After an upgrade of a busy server to Oracle Solaris 10 9/10, I notice a process called zpool-poolname that has 99 threads. This seems to be a limit, as it never goes above that. It is lower on workstations. The `zpool'' man page says only: Processes Each imported pool has an associated process, named zpool- poolname. The threads in this process are the pool''s

Pre-fletching on the file and device level has been disabled yielding good results so far. We''ve lowered the number of concurrent ios from 35 to 1 causing the service times to go even lower (1 -> 8ms) but inflating actv (.4 -> 2ms). I''ve followed your recommendation in setting primarycache to metadata. I''ll have to check with our tester in the morning if it made

Looking for a little help, please. A contact from Oracle (Sun) suggested I pose the question to this email. We''re using ZFS on Solaris 10 in an application where there are so many directory-subdirectory layers, and a lot of small files (~1-2Kb) that we ran out of inodes (over 30 million!). So, the zfs question is, how can we see how many files & directories have been created in
