OT: AF 4k sector drives with 512 emulation
Still have good quality older sata hardware raid cards that require 512 bytes/sector. As far as I know HD manufacturers are not making native 512 bytes/sector drives any more. Some have better 512e emulation than others. Looking for some advice on which to avoid and which are recommended. Thanks. PS this is for a CentOS6 server.

Centos 7, grub2-mkconfig, unsupported sector
Hi, folks, Well, I get back from vacation, and three CentOS 7 boxes didn't come up this morning (my manager and the other admin did the update & reboot). On these three - but *not* another one or two, and I don't think those others are Dells, they're supermicro's - the 327 kernel fell into the rdosshell, I guess. I finally got one the three up by going back to the 228.14

ext4, 4k sector alignment
I've mentioned this problem before but put off doing anything about it and maybe now someone can suggest the best solution. I have a 3-member RAID1 set where one of the members is periodically swapped and rotated offsite. The filesystem contains a backuppc archive which has millions of hardlinks that make it impractical to copy with a file-oriented approach. The current filesystem is

Syncying and upstreaming 4k sector patches
Hi, time ago I started doing support for 4k sector disk for syslinux. Patches worked for my cases (ext) and did not introduced regression problems with normal disks. Now I would like to update these patches and upstream them. It's not clear however which is the branch I should use to rebase these patches. Previous patches was against syslinux-4.06 but now there is syslinux-5.01 (elflink)

Sector size on 7K3000 drives?
Hi al Does anyone here that knows if the new 7K3000 drives from Hitachi uses 4k sectors or not? The docs say "Sector size (variable, Bytes/sector): 512", but since it''s variable, any idea what it might be? I''m planning to replace 7x3+1 drives on this system to try to get some free space on some full VDEVs. If the drives are in fact 4k sector drives, will it be possible

Migrating zpool to new drives with 4K Sectors
Hi ZFS Discuss, I have a 8x 1TB RAIDZ running on Samsung 1TB 5400rpm drives with 512b sectors. I will be replacing all of these with 8x Western Digital 2TB drives with support for 4K sectors. The replacement plan will be to swap out each of the 8 drives until all are replaced and the new size (~16TB) is available with a `zfs scrub`. My question is, how do I do this and also factor in the new

Status of support for secotr sizes >512b
Hello, can someone give me a short summary on the status of support for sector sizes >512bytes in SYSLINUX? The installer obviously still doesn't support it, at least it complains about "unsupported sector size" when used on a 4k-sector disk. I read somewhere that this is only a problem of the installer, and that SYSLINUX itself would work if it got installed "by other

Question on 4k sectors
Hi. Is the problem with ZFS supporting 4k sectors or is the problem mixing 512 byte and 4k sector disks in one pool, or something else? I have seen alot of discussion on the 4k issue but I haven''t understood what the actual problem ZFS has with 4k sectors is. It''s getting harder and harder to find large disks with 512 byte sectors so what should we do? TIA...

RHEL/Centos6 handling disks w/4k sectors?
Does anyone know if 4k sectors will be handled better by the kernel in Centos6? I'd like to copy backups to a 750Gb laptop type drive for offsite storage but the best write speed I can get is about 8MB/sec even with dd to the raw disk which shouldn't have an issue with partition alignment. -- Les Mikesell lesmikesell at gmail.com
