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 disk...

I have a couple development servers running centos 6.3 64bit that have LSI 9211-8i SAS2 controllers connected to a SAS2 backplane. these work fine with SATA hard disks (populated with a bunch of 3TB SATA drives)... I'm trying to install a OCZ Vertex3 SSD on each of the two servers to do some ssd caching tests... system sees the drive, so I do the following... # part...

I have an older Dell PowerEdge server with one hard drive, with CentOS 7 currently installed. I wanted to do a clean install of CentOS 8, but it doesn't pick up the hard drive. When I click on the destination to pick the hard drive it only shows the USB drive that I'm installing from. I checked for a RAID configuration on the server, but there is only one disk, and no RAID is configured.

Dear All, It may be this not the correct mailing list, but I''m having a ZFS issue when a disk is failing. The system is a supermicro motherboard X8DTH-6F in a 4U chassis (SC847E1-R1400LPB) and an external SAS2 JBOD (SC847E16-RJBOD1). It makes a system with a total of 4 backplanes (2x SAS + 2x SAS2) each of them connected to a 4 different HBA (2x LSI 3081E-R (1068 chip) + 2x LSI SAS9200-8e (2008 chip)). This system is has a total of 81 disk (2x SAS (SEAGATE ST3146356SS) + 34 SATA3 (Hitachi HDS722020ALA...

...-) I have a Sun RAID card which I am pretty sure is LSI OEM. It is a 3G/s SAS1 with 2 external connectors like the one on the right here : http://www.cablesondemand.com/images/products/CS-SAS1MUKBCM.jpg And I have 2 x Sun J4400 JBOD cabinets each with 24 disks. If I buy a new card that is 6G/s SAS2 with the same connector, can I connect my cabinets to it and have them work? Even if they only work at 3G/s I don't care. I've also hit an issue with the number of logical devices allowed, and am wondering whether this might be a HW, FW or SW limitation if anyone knows. I want to run eve...

...tty bad. If you are lucky you can import the pool read-only and migrate it elsewhere. I''ve also tried setting zfs:zfs_recover=1,aok=1 with varying results. http://docs.oracle.com/cd/E26502_01/html/E28978/gmkgj.html#scrolltoc Hardware platform: Supermicro X8DAH 144GB ram Supermicro sas2 jbods LSI 9200-8e controllers (Phase 13 fw) Zuesram log ZuesIops sas l2arc Seagate ST33000650SS sas drives All four servers are running the same hardware, so at first I suspected a problem there.

...#39;m going to guess thats a desktop grade SATA disk spinning at most at 7200rpm (many are slower, 'green' disks are often 5400rpm). what sort of workload are you running? our high disk IO servers, doing things like transactional databases, have many 10000rpm or 15000 rpm drives on a SAS2 raid card with 1GB or 2GB of write-back-cache (battery or flash backed). -- john r pierce 37N 122W somewhere on the middle of the left coast

I know with the SAS2 chips (SAS2008, SAS2308, etc), FreeBSD strongly recommends the firmware revision matches the driver revision, so if the driver is P20, the firmware also should be P20. I don't have any SAS3 stuff. -- john r pierce, recycling bits in santa cruz

There was a recent thread about Redhat's removal of drivers from LSI SAS2, it's probably the problem you are facing. It can be worked around with the help of Elrepo repo. https://lists.centos.org/pipermail/centos/2019-October/173682.html https://elrepoproject.blogspot.com/2019/08/rhel-80-and-support-for-removed-adapters.html https://elrepo.org/linux/dud/el8/x86_6...

Hi, since some time ago we do have a lot of "timeouts" connecting to our imap/po3 server. This week I switched the whole system to a new dual quadcore xeon, 24GB RAM, SAS2 RAID-10. (SUN Fire 4170) But the mailclients (mostly thunderbird and apple mail) still reporte the timeouts by accessing the mailboxes. The server is doing smtp, imap/pop3, webmailsystem and spam/antivirus-checking all together. (RH EL 5, sendmail, horde, mysql, mailscanner, spamassassin) We use...

Does anyone know if a PERC H200 is a real RAID controller? I'm about to build a box to CentOS 6.5 (it was Windows...) with RAID 6 on Monday, and this PE R610 has this.... I'm familiar with PERC 6 and 7s, but just dunno 'bout this one. mark
